Good morning and welcome to this lecture in our course on chemical engineering principles of CVD process. In the last few lectures we have been looking at the transport processes involved in CVD systems particularly mass transport but at the same time recognizing the influence of other types of transport phenomena on the mass transfer process that are taking place in a CVD system and earlier we had also looked at the thermodynamic aspects but the focus in the last few lectures has been on how to define control volumes and conservation equations for CVD reactors, how to write the appropriate constitutive laws, how to calculate the relevant dimensionless mass transfer coefficients such as Nusselt number, Stanton number and capture efficiency and also how to apply correction factors appropriately when there are phenomena occurring that cause the process to deviate from its nominal values. So whenever you have an augmentation effect such as a phoretic effect or an inhibiting effect such as kinetically limited homogeneous or heterogeneous reactions the effect of these phenomena have to be incorporated as suitable correction factors in the expressions for the Nusselt number and Stanton number. So we also looked at how we do that. For the remainder of the course we are going to be looking at some specific CVD reactor configurations that are commonly applied in the industry and as we do that we will try to also assess how thermodynamic and transport principles would apply in each of these cases. We will start with CVD reactor configuration that is actually modeled on the tungsten filament bulb that we had discussed in one of the earlier lectures. If you remember we said that one of the causes for bulbs to be thrown away is when there is substantial loss of tungsten material from the filament which deposits and coats the walls of the bulb causing a loss of light transmission. So it is a process that is CVD because the bulb is filled with a reactive environment. It is not just filled with air or inert gases it is actually has a halogen filling and if you recall the reason for this halogen filling inside the bulb is to provide a reactive chemistry that will continuously bring tungsten back to the filament even while depletion of the tungsten is going on. So if you can establish a steady state between the two in theory a bulb can last forever but it is clearly an undesirable process. In the case of an electric bulb you want to minimize the tungsten loss from the filament you want to minimize deposition on the bulb ball and so on. But somebody had the bright idea why do not we use that same concept to actually intentionally deposit films on substrates. So if you can actually design a CVD reactor that kind of looks like a bulb then you can use what is going on inside an electric bulb but in a positive and productive manner. So that was the idea behind this type of CVD process. The basic concept here is quite simple. You provide a very hot location within the reactor which causes dissociation of the reacting species that come to the vicinity of that hot material whatever it is, it could be a simple wire, it could be a filament, it could be ribbons but some source of high heat which will cause dissociation to happen inside the CVD reactor and then the dissociated species will transfer to the substrate and deposit as a film on the substrate. Now this concept was introduced first in 1979 and it was called thermal CVD. In 1985 the name was changed to catalytic CVD and for about another 6 years or so people continue to refer to this mode of chemical vapour deposition as catalytic CVD and then in 1991 the name was again changed to hot wire or hot filament CVD. Now the reason for you know calling it thermal CVD or hot filament CVD are obvious. I mean basically you are introducing a hot zone inside the CVD reactor and causing the species vapour species to be generated because of that hot source of heat but the reason for calling it catalytic CVD is not so obvious but what it refers to is the fact that if you want to take silane and reduce it directly to silicon you have to make the silane molecule lose you know 4 hydrogens simultaneously. So it takes a lot of energy to make that happen whereas if you use this type of a hot wire or catalytic CVD essentially you set up a sequence of steps.  So when you set up the reaction sequence that way it turns out that the energy barrier or the total energy input required to convert silane to silicon is much smaller. So essentially this hot filament has played the role of a catalyst by lowering the activation barrier for the conversion to happen and that is the idea behind calling it a catalytic CVD reactor. The advantages of this type of reactor are that it provides a very intense source of energy within the reactor geometry itself. So it obviates the need for example for introducing plasma into the reactor where plasma would be another source which can also help in the dissociation of the gas molecules. But anytime you use things like plasma in a reactor you add both to the cost as well as complexity of the equipment. So the hot filament CVD process substantially reduces the energy input to the system to make CVD possible. The other advantage of the hot wire type of CVD reactor is deposition rates can be quite high. It all depends on how hot you can get the filament to without causing loss of material from the filament itself. And so for example if you tungsten or tantalum as your filament material you can heat it up to close to 1800 degree centigrade or even close to 2000 degree centigrade. So those are very high temperatures and they can cause a complete molecular dissociation of the reactants that you are feeding into the CVD system. Another advantage of the hot wire type of CVD reactor is that the reactor configuration itself is quite simple. So again what you are really looking at is an extension of a bulb. So in the normal CVD reactor you would have a substrate to which you are providing some source of energy and so you have your wafer sitting here and the gases are flowing in some fashion over this reactor and the deposition process takes place over here. So the reactants are preheated before they enter the reactor and typically you use a cold wall configuration to ensure that the deposition only happens on the substrate. So this is one variant of design of a CVD reactor and here of course the wafers can either be horizontally oriented or they can be vertically oriented or they can be oriented at angle. You can do a single wafer at a time. You can do a batch of wafers. There are lot of variations that you can build into the design of this type of a CVD system which is called HF CVD, you know horizontal flow CVD reactor. That is possibly the most commonly used CVD reactor configuration primarily for bulk production of silicon wafers. Another variant on this that we discussed is a stagnation flow reactor where the reactants enter in a vertical flow setting up a stagnation layer around the substrate which helps in terms of maximizing the residence time of the reactant species and therefore maximizing the deposition rate and the uniformity of the film on the surface as well. And the stagnation flow CVD systems are also used quite commonly in various applications. Now one of the limitations of both these methods is that if you look at actual utilization of your feed gases, for example if you are feeding in let us say 100 kilograms of silane how much of that really gets reduced to silicon and how much of it is essentially vented out as you know exhaust gas. The utilization is quite low particularly in the horizontal flow system it is less than 20 to 30 percent because it is only the layer of the silane molecules that come in direct contact with the substrate that are likely to deposit the silicon film. The utilization is a little higher in the stagnation flow system although it depends on the molecular weight of the reacting species. The higher the molecular weight of the reacting species the greater is the probability that it will inertially separate an impact on the substrate and cause film formation. But if the reactant molecules are lighter then they are more likely to follow the streamlines of flow of the carrier gas and it is quite possible that again the rate of incidence on the substrate and therefore the efficiency of conversion of the reactant species to product film can be quite low. One of the major advantages of the catalytic CVD or hot wire CVD reactor is that the conversion is extremely high. If you introduce silane into a CVD reactor with a hot filament the likelihood that the SIH4 will break down and form silicon atoms that actually impact on the substrate is quite high. It can be as much as 40 to 50 percent I mean you are never going to get close to 100 percent however 40 to 50 percent is quite achievable. The disadvantages of the hot filament CVD reactor the first one is you know the controlling the temperature of the filament. Filament temperature becomes one of the key variables here. The filament material does not play a huge role as long as you know you make sure that it is vapor pressure is low. For example you do not want to use carbon or graphite as your hot filament because the carbon can evaporate from the filament and then be included in the film as a contaminant. But tungsten, tantalum, platinum, rhenium there are many materials that satisfy the requirement that you have to be able to heat it up to a very very high temperature without causing loss of material from the filament due to evaporation. So 1500 to 2000 degree centigrade is you know easily achievable with the use of such materials. However control of the temperature can be quite important because the dissociation efficiency depends quite sensitively on the filament temperature. So that is one of the issues but the larger issue and the one that limits the efficiency of such reactors is the fact that you know you have to somehow control the flow of the dissociated species in such a way that close to 100% of the species encounter the substrate. Now a normal hot wire CVD reactor the way that it is configured would be so instead of this in a hot wire CVD reactor the way you would do your deposition is that you will still have a substrate holder on which you will be forming the film and it still requires some energy input but what you will do here is essentially have a hot filament somewhere inside the reactor it can be a single filament it can be an assembly of filaments they can look like fingers they can look like ribbons there are many configurations of these filaments that are possible. So this Tf will be kept if this is Tw Tf will be much greater than Tw and if this is your chamber walls again Tw will be much greater than Tc normally. So let us say that you know we have silane in this system so silane is impacting the filament and getting dissociated into Si and H you can also have hydrogen as a carrier gas and even hydrogen will dissociate and form H radicals when it encounters the filament. How do you ensure that all these dissociated molecules flow down and actually impact the substrate so placement of the filament is one issue the second is controlling the flow in the system. Now this type of reactor is naturally 3 dimensional the flow will tend to go essentially the species that you are generating there is no preferential direction for them to go so they will it is a diffusion controlled reactor typically diffusion control means that you know diffusion is a random walk process. So the direction in which the dissociated molecules move is entirely random so there is no preferred orientation of motion of these dissociated molecules which implies that you are not really directing them towards the substrate you are allowing them to go wherever they want to go and then hoping that some of them will impact the substrate. So a better way to do that is to introduce convective flow and use the convective flow to essentially turn this 3D geometry into a 1D geometry so if your filament is located here then you would want to provide a vertical flow so that all the dissociated molecules are convicted towards the substrate or if your filament is located upstream of the wafer then you would want to direct your convective flow in this way so that you kind of overcome the diffusional motion of the dissociated molecules and force them to encounter the substrate. So you have to pay a lot of attention to the temperature control of the filament as well as the transport characteristics of the gas the carrier gas to ensure that you are getting maximum dissociation efficiency at the filament and also the dissociated species are being made to encounter the substrate to the largest extent possible. So if I look at the design parameters in this system what are we trying to optimize it is basically the rate of film growth let us call that some G which is number per basically the number of silicon atoms for example that are actually depositing on the substrate as a function of time. Now this is the output parameter that you want to control so what are the input parameters that are at your disposal the rate of supply of the depositing molecules is another one so you can call that let us say some F so it is the rate at which you are feeding in the reactant molecules into the system to make the film. So obviously G by F represents your deposition efficiency and it is this efficiency parameter that you want to try and optimize. So what do you have at your control to try and optimize this when you look at what is going on F is your input feed and G is the rate at which the film is forming on the substrate but what is the link between the two it is what is happening at the filament. So you have to look at what is going on at the filament so the first thing that you need to know is what is the dissociation efficiency where we define dissociation efficiency as the probability of one SiH4 atom dissociating into one let us call that dot or atom. So SiH4 would go to SiH3 and similarly SiH3, SiH2, SiH so on. So every atom that strikes this filament you have to look at the probability of that getting dissociated into its next lower form and because that kind of leads you in the direction of forming silicon from SiH4 so that is one critical variable. The other critical variable would be the rate at which material is actually being supplied to the filament. So if you call that some gamma filament this refers to essentially the flux of silane molecules that are striking the filament. The flux is given by 1 by 4 rho times V where rho is the density of the silane molecules and V is the essentially the thermal velocity at which the molecules are striking the filament. So this gives you essentially the number of molecules of silane striking the filament per unit time per unit area. So if you take this and multiply it by the effective area of the filament let us look at it as a cylinder, model it as a cylinder. So it is pi Df times Lf so this gives you the rate at which the silane molecules are actually striking the surface. So this is the rate of incidence of SiH4 slash SiH3, SiH2, SiH at on the filament. So if I look at, if I take the ratio of this gamma parameter 2f this gives you an efficiency of filament impact. It tells you what percentage or what fraction of feed molecules are actually striking the filament at any given point of time and then when you take the dissociation efficiency that tells you what is the probability that a molecule that strikes the filament will get dissociated into its next daughter molecule. So essentially this eta filament impact multiplied by eta dissociation gives you the efficiency with which the dissociated molecules are being supplied to the system. So in essence this eta dissociation times the eta filament impact should determine the deposition efficiency. In fact there is an empirical relationship that has been obtained which relates the 2 as 1 minus eta deposition equals 1 minus eta D times to the power 4. So clearly there is a link between the 2 and of course some of these parameters themselves are also related to each other. So what we have presented here is a very simple kind of a mechanistic analysis of what is going on in the system and the fact that you know we have several efficiencies in the system that are linked to each other and each one must be separately optimized, right. If you are trying to optimize the deposition efficiency you have to A make sure that you are providing a path for the feed molecules to encounter the hot filament and B you have to make sure that you are operating the filament under conditions that cause as completed dissociation of the molecules as possible and finally you also have to make sure that you provide a transport path for the dissociated molecules to come and strike the substrate, right. So all of these kind of go together to establish the overall true efficiency of the system and as I said eta deposition of roughly 40 to 50 percent is achievable in a hot wire CVD system which is actually considered acceptable. So essentially there will be a recycle loop provided so that the feed silane and hydrogen that escapes without being converted will essentially be captured and brought back into the CVD system so that there is no wastage of the feed material because silane is an expensive precursor to use in such systems. So if you look at this from a thermodynamic and transport point of view thermodynamically it is a very favorable system because you are able to achieve extremely high temperatures at the filament and as we discussed before the higher the temperature the closer to chemical equilibrium you can get which represents a maximum rate that you can achieve. So the thermodynamics are certainly very favorable in such systems. The transport aspects you know here as we have done before you have to break it into you know m dot in this case we are looking at the deposition of silicon element it is going to be a combination of m dot silicon convection plus poruses plus diffusion. So if you look at this what is favored in such reactors diffusion is also favored primarily because the hot filament enables you to dissociate the compounds into their virtually into their elemental state and the lighter the molecule the greater will be its diffusion velocity. So the typical diffusion fluxes diffusion velocities that you see in a hot filament CVD reactor are substantially higher compared to the horizontal flow CVD systems or the stagnation flow type of CVD systems. So that is good. Poruses you know the major phoretic effect in this case will be thermophoresis because the presence of a hot filament introduces a very steep temperature gradient. So now whether that helps you or hurts you depends on the diffusing species as I said in one of the earlier lectures. If the diffusing species is lighter than the carrier gas then thermal diffusion occurs down the temperature gradient from hot to cold. So in that case it helps basically you the thermal diffusion will be an additional factor that drives the diffusing diffusing species from the hot filament towards the substrate but on the other hand it can also drive diffusion towards the walls of the chamber. So there could be more losses due to unintended deposition around the chamber walls but you know in general as long as you are using a diffusing species that is lighter than the carrier gas you are okay. Now in the case of other types of phoretic phenomena that are present typically they are negligible compared to the thermal diffusion process that is going on. Now when you look at convection that is where you have to you have a lot of flexibility in terms of how you design the system to adjust that parameter you can essentially leave it as simply a hot filament with some nominal flow across the CVD reactor or you can play around with this convection process to maximize the rate at which species is delivered to the system. So in general I would say diffusion is favorable, phoresis is flavorable, convection is questionable unless you intentionally force the convection process to happen in such a way that the dissociated species are brought to the material I mean to the substrate. Now this is the rate at which deposition flux is happening towards the surface however if you look at the rate of growth of the film while there is related to this it also depends upon the surface accommodation and surface diffusion characteristics of the substrate on which deposition is happening. So when you look at that part of it you know the capacity of the substrate to absorb the species and build a continuous and uniform film with it the hot filament type of CVD reactor in some ways is not advantageous because in order for a uniform film to form one of the things you look for is you know very uniform temperature of the surface because that the surface temperature is the number one factor that drives surface diffusion and therefore has a significant influence on the uniformity of the film and also the surface temperature dictates the rate at which molecules are arriving and dissociating from the surface. So the coverage at any location as well as uniformity of the coverage on the substrate are both dictated by the temperature distribution on the substrate and the way that hot wire CVD reactor is set up you know when you have a fairly intense source of heat at one location and then the rest of the reactor is being driven at much lower temperatures it is not easy to achieve uniformity of temperature. So that can also be a negative factor in use of a hot wire CVD system your rates of deposition can be quite high because of the high utilization efficiency but the uniformity is something that you have to kind of keep your eye on because it is quite easy for that to be adversely impacted because of the way that this type of CVD reactor is designed. In fact you know when thermal CVD was introduced like I said back in 1979 time frame after couple of years it completely vanished because people were experiencing all kinds of problems with it. They were getting huge masses of material but it was arriving in a way which was not really conducive to use that film later in the process. So about 4 years people kind of said that is not use this process but others started working on it and tried to kind of iron out some of the problems associated with hot wire CVD and have now brought it to a stage where it is again a commercially viable process but at the same time you know it is something that you have to use with caution and it does require more controls on both uniformity of temperature and uniformity of flow compared to the more conventional horizontal flow CVD reactors or stagnation flow CVD reactors. Now the type of materials that are deposited in such reactors can be again a wide variety. Silicon is probably the most commonly deposited film using hot wire CVD but another one which is kind of interesting is Teflon or Teflon as you know is basically a barrier material it is a polymer it is a very inert material chemically inert it provides excellent protection against corrosion, erosion many kinds of phenomena Teflon is essentially a non-sticky surface so Teflon coating for example is used even in cooking vessels right. So Teflon is a commercially very important product and the deposition of Teflon has always been a challenge again from the uniformity viewpoint and also the adhesion and cohesion viewpoint you know when we say adhesion it is basically the sticking of the Teflon film to the substrate that you are trying to coat and cohesion is essentially the interlayer adhesion in the Teflon film itself. Both are very crucial for the deposited Teflon film to be usable and to be useful. So CVD particularly the hot wire CVD process has gained favour as a method for depositing Teflon because it offers certain advantages. In a hot wire CVD reactor to make Teflon film you use something called HFPO as your precursor it stands for hexafluoro propylene oxide which has the configuration of CF3, CF, CF2OO. So what you try to do is break this down into CH3 or CF3, CFO plus CF2. So the CF2 is your monomer that is essentially used to build the Teflon polymer. So CF2 will combine with another CF2 to form C2F4 and you continue this process until you make Teflon which is basically a CF2N type of polymer. So clearly when you are trying to make Teflon as a film the most important part of it is the dissociation part. You have to be able to dissociate the HFPO molecule into CH3, CFO and thereby releasing CF2 and the CF2 then has to be transported to the substrate and made to deposit. So clearly what you do here is use the filament as your heat source to cause the dissociation to happen. Once the CF2 forms you still need to provide a reactive environment so that the CF2 molecules can keep associating with each other and ultimately forming a fully assembled polymer film on the substrate which is Teflon. So if you look at some of the challenges of making Teflon coatings and the reason that the hot wire CVD reactor is quite advantageous for this process is that the presence of the hot wire provides your dissociation mechanism right, that part is obvious. Now how do you again get the CF2 to link to other CF2 molecules? You have to provide a chemically reactive environment again with high temperatures being present and provide also sufficient energy so that the homogeneous kinetic barriers are overcome because in order for a CF2 molecule to combine with the CF2 molecule in the gas phase and form a C2H4 takes energy. And so in a system where for example let us say that you are just using a heat source to do this initial dissociation how do you go from that to form a Teflon film? You really cannot. Now the advantage of doing this in a CVD reactor is between the time that this dissociation happens and the time that you have to form this molecule you are providing sufficient residence time as well as a flow path inside the reactor where these association reactions can continue and you can keep forming higher order molecules to the point where at the substrate where now you have a heterogeneous equilibrium it becomes thermodynamically favorable to form Teflon solid. So the solid Teflon coating only forms at the substrate by controlling again the temperature of the substrate and by taking advantage of the fact that in order for the CF2 molecules to combine in sufficient density and close spacing to form a solid material you need a heterogeneous equilibrium. In other words it is very unlikely that you will form Teflon particles in the gas phase. The homogeneous reaction barriers the kinetic barriers are just essentially too large to allow the formation of Teflon particles in the gas phase but as soon as you introduce a substrate and you introduce heterogeneous chemistry the energy barrier for formation of a solid Teflon film is instantly lowered. So the probability of forming solid Teflon suddenly essentially goes from 0 to 1 it is a binary process. Now again in reality what may happen is in the gas phase you may start seeing some nuclei of Teflon forming but these are typically going to be smaller numbers and they will also be deposited onto the CVD film by particle transport or aerosol transport. So they may show up as defects when you inspect your Teflon film after the CVD process. One of the things you would look for is the presence of any of these little you know protrusions on the film which may suggest that some material has deposited in particulate form. Actually then what you would do is essentially as scrubbing or polishing or cleaning process that will dislodge any particulate material that has deposited on the film and leave behind a smooth Teflon film. So the post deposition inspection and if necessary treatment may be required in order for you to obtain a nice smooth CVD film. In fact in one of the later lectures we will talk about what are called aerosol CVD reactors. The formation of the aerosol in the gas phase while it is normally something to be avoided can sometimes be actually used purposefully to make certain types of CVD films and CVD coatings especially. So there are special types of CVD reactors that are called aerosol CVD reactors or CVS reactors chemical vapor synthesis reactors that we will talk about later which actually promote homogeneous nucleation and the transport of particles in addition to transport of vapors to form films on substrates. So the use of the hot wire CVD reactors to form polymeric films is also widespread because polymer CVD films are you know quite sensitive to substrate temperature. So it really cannot increase the substrate temperature too much but the filament temperature you have much more control over you can make the filament as hot as possible. You may recall that in order to make polymer films you have to use low temperatures and typically plasma you know plasma enhanced CVD particularly in ultra high vacuum conditions is normally what is used to make polymeric films by CVD but that again introduces a high cost and the equipment design can be quite complicated if you have to go that way. So the hot wire CVD process in the case of polymeric films provides a commercially viable alternative to the use of high density plasma for making polymer films and again the advantage of this is typically when you use a Teflon coating you are not looking for angstroms of thickness you are looking for or not even nanometers you are typically looking for microns of thickness and it is very difficult to get microns of film material on a substrate using plasma enhanced CVD or any of those other techniques because they are more for molecular level self assembly type of film formation. So if you want to get a Teflon film or any polymer film that has sufficient thickness then you are much better off using some kind of a hot filament type of CVD process rather than one that uses plasma as a way of dissociating the molecules and also energizing the substrate. The only other thing you have to keep in mind is when you are doing polymer deposition on a substrate the substrate preparation prior to CVD is also very critical. The surface has to be extremely clean at a molecular level and it has to be at sufficient energy to be able to capture the molecules that are depositing. So usually the substrate does get pretreated with some kind of energization process. It could be using heat or it could be using plasma in fact the plasma treatment instead of applying it to the entire CVD system and trying to dissociate the gas phase species. In the case of hot wire CVD particularly for deposition of polymeric films the use of plasma irradiation is usually confined to the substrate only in order to increase its surface energy. Any time you take a substrate and you expose it to the impingement of plasma it causes the surface energy to increase and as the surface energy increases the force of adhesion between the film and the substrate increases as well. So some either pre-tiptoin of the substrate or post treatment such as baking or thermal annealing of the film may be required in order to increase the hardness of the film and also the adhesion of the film to the substrate on which you are depositing it. Alright so the reactor that we have discussed today is the hot wire CVD reactor. In the next few lectures we will look at a few other configurations of CVD reactors and we will try to highlight what are the advantages and disadvantages of the various types of systems and you know what type of reactor configuration you would like to choose for the different products that you are trying to make. Any questions on what we have covered today? Conviction, it is basically unidirectional flow. For example you know the filament is on top of the substrate essentially you introduce vertical downward flow right and there are systems that are available you know you can essentially use a shower head type of configuration. You will have multiple nozzles through which you can introduce your carrier gas but do it all in such a way that it is essentially a vertical laminar unidirectional flow that will force all the vapors to then get transported. It is the same way that clean rooms are designed for example. It prevents turbulence, it prevents mixing and it causes the flow to be in one direction and similarly if the filament is upstream of the substrate you will use horizontal laminar flow so same purpose. The key things are unidirectional and lack of turbulence.


Our mission is to provide trained, doctrinally sound OCTs to Army Guard Brigade Combat Teams during their collective training exercises. Specifically, we focus on the Exportable Combat Training Capability Exercise or XCTC. Here at OGW, you'll develop a solid foundation based on Army Doctrine. Overall, this organization will help develop you into a better soldier, leader, coach, and mentor. Valuable lessons and skills I've obtained are leader development, refined organizing, planning, preparation, and execution of op orders. I think the biggest things I remember is interacting with units from across the National Guard formation, seeing what other capabilities are for other warfighting functions and what they bring to the fight that I was not not well first in prior to coming here. Just being able to go through the First Army Academy and then our own personal GW Academy going through how we do trained models and the depth that we put into them with the details and being able to take that back to the guys and then just going through orders, process, TLPs and really hone those skills more so than seen on the traditional side. I started as an ADO soldier then transitioned to Title 10 AGR. During my tenure here at OGW, I've had tremendous opportunity to accomplish new achievements. Here at OGW, I've earned my EIB Ranger Tab and Parachute Dispatch. I came to OGW for the opportunity to learn, experience something outside of my state that wasn't readily available there and expand my home capabilities. Soldiers that come to Obscrup Wolf will gain a tremendous amount of experience executing large-scale ground combat, collective training exercises from the platoon through the brigade level. When a soldier returns to their home station from Obscrup Wolf, they will be a more experienced, more rounded and more doctrinally sound leader.


Hello, and welcome to this video explaining how to migrate an STM32 Cube-based application between different STM32 series. This video provides guidelines through a practical reduced cost application example by migrating an STM32F4 application to the STM32L0 series using STM32 Cube with ARMKyle IDE. Now, let's start with a project using the STM32 Cube F4 package running on STM32F411 Nucleo, using an ADA Fruit 1.8-inch TFT shield with joystick and microSD card. First, search for the STM32 Cube F4 package on www.st.com. Click the STM32 Cube F4 link and search for the STM32 Cube F4 software package. Save and unzip it to a local directory. Once this is done, download the STM32 Cube L0 package. Now, open the STM32F411RE Nucleo project and compile it. Before running the project, open the doc directory here and look at the readme.txt file to learn how to operate the demonstration application. Now, let's start the migration process. First, change the device target in the option for target tab sheet. In our case, we are going to migrate the code to the STM32L053R8 Nucleo. Now, we are going to replace the specific library and product files. Replace the device startup file, the device interruption file, the Nucleo board driver file, the device CMSIS driver, and the device hardware abstraction layer files. Then add the new file in the project directory that you want to migrate by right-clicking on the project directory to add the new file. As a startup file, we can use the template given for the STM32L053 device located in drivers slash CMSIS slash device slash ST slash STM32L0XX slash source slash templates slash ARM directory of the STM32 cube FWL0 package. Now, remove the STM32F411 file. Then, create your new interrupt file. You can get help with examples from the different Nucleo projects or you can also copy and change the name of the original interrupt file then change the include file name to STM32L0XX underscore IT dot H and map your application interrupts according to your new hardware. In our case, the user button is on EXTI4 underscore 15. Replace the file STM32FXX underscore Nucleo dot C with the STM32L0XX underscore Nucleo C file located in the drivers slash BSP slash STM32L0XX dash Nucleo directory of the STM32QL0 package. Also, replace the file system underscore STM32F4XX dot C with the file system underscore STM32L0XX dot C located in drivers slash CMSIS slash device slash ST slash STM32L0XX slash source slash templates directory of the STM32QL0 package. And now, replace all driver files used in your application located in drivers slash STM32L0XX underscore HAL underscore drivers slash SRC directory of the STM32QL0 package. Change the defined names in the C slash C plus plus tab sheet and change the related include path of the source files that you have changed. Now you see that red crosses appear in your code. Don't worry, a few adjustments remain to be done. You have to update all old product references with your new file names here in main dot C and dot H files. Now change your STM32F4XX underscore HAL underscore CONF dot H file to STM32L0XX underscore HAL underscore CONF dot H. The easiest way to perform it is to take one of the examples provided in the cube package and customize it for your application. For example, we can use the one in the projects slash STM32L053R8 dash nucleo slash demonstrations slash ink directory. Here you have to uncomment the defines according to the hardware peripherals and associated driver files used in your project. The last adaptation to perform is inside the system clock underscore config in the main dot C file. Here again, you can paste the code from one of the examples provided in the L0 cube package. We can use this BSP example in the STM32L053R8 dash nucleo directory. Simply copy and paste the code of the function into your main file. Now all the errors have disappeared. You can now compile your code. You can see that no errors remain. The code was successfully migrated. Verify the programming tool settings. Set the flash loader for the STM32L0 and select ST link v2. Now load and run your application. Let's now test your application and fine tune your new code. Here the demo name should be nucleo dash L053R8. You can see the difference of performances between the STM32L0 and STM32F4 nucleo demos. We have seen how to migrate a cube based application between two different STM32 series.

Streaming music can be done in many ways. The Watson-Amazin Analog is perhaps the easiest way if you are in for a somewhat upmarket solution. Watson is a new brand, founded by the Swiss company Engineered Electronics. And it currently only has two products, the Amazon Digital and the Amazon Analog. Both enable playing music from a computer over the network to your stereo. In this review the Amazon with Analog outputs. Let's see where it fits into your stereo. You need a stereo with a free analog input on your amplifier. The two RCA's on the Amazon Analog have to be connected to a stereo line input on the amplifier or receiver, for instance the CD or AUX input. The network connector on the Amazon is then connected to the network router using a network cable. There is no Wi-Fi option. You now have access to internet radio and tidal and cobus streaming services using the free Watson Music app on iOS or a DLNA app for Android or iOS. If you run a DLNA server program on your computer or NAS, you can play music from there too. The DLNA server program and controller apps are widely available for Windows, Mac OS, Linux, Android and iOS. Alternatively you can install Roon on the computer and use the Roon remote function on the smartphone, tablet or computer. Roon supports Windows, Mac OS, Linux, iOS, iPad OS and Android. Airplay is also supported. The Amazon Analog has a remarkably shaped housing with a beveled edge on one side. It measures only 104 x 87 x 38 mm and weighs 382 grams. On one side we find the right and left analog outputs on RCA connectors. A small red LED on the left shows the device is powered on, while on the right a red LED shows that the music is playing. On the rear a 5VDC power input to connect the supplied worldwide power supply tool. Next to it the network connector. That's all folks. No knobs, no buttons, no settings, it just works. Next we find the larger circuit board with piggyback on it a small board computer based on a Texas Instrument ARM Cortex-AX processor that also handles the network functionality. Despite the fact that it can run at a gigabit per second, it is programmed to work at 100 megabit per second for sound quality reasons. There is a DDR3 memory and an eMMC Nound Flash Drive, both by Samsung. On the main board we see low drop-out voltage regulators and an ARM Cortex-M0 microcontroller. The analog output circuits are found here with the SiriusLogic-slash-Wolson-WM8742-GEDS DAC chip here and two clock crystals close by. As said there are no controls on the Yamersen analog. If you own an iOS device you can use the Watson Music app which is a proprietary DLNA controller that supports Cobus, Tidal and internet radio. So you don't need to install anything apart from the Watson app of course. Since DLNA is an open standard you can use any DLNA app on a smartphone, tablet or computer. The possibilities then depend on that app. I normally use Glider as DLNA app and it worked here too, but I prefer the Watson Music app. Another way of using DLNA is by installing Audirvana 3.5 on your computer. It will immediately recognize the Amazon Analog. Especially Audirvana users that have their computer connected over analog directly to their stereo will improve the sound quality enormously by using the Amazon Analog. Also using a moderately priced USB DAC will sound considerable less. By using the Audirvana Remote app you can place the computer elsewhere in the house and control it from your smartphone or tablet. Another option is to install Roon on a computer. Here you have to activate the connection first by going to Settings and Audio. Look for the Amazon Analog and give it a name. You then select it. If it is your only Roon endpoint it will be the only entry here. Again, you can control Roon from a smartphone or tablet. Apple Airplay is also supported so you can play music directly from Apple Music, aka iTunes or other Apple devices that can function as a source, like iPhones and iPads. In all cases the volume can be set from the app you use to control playback. It's about the easiest setup I know. Audirvana and Roon are not free. Apple Music comes free with Apple products. The Amazon products can be updated when necessary. First download the update file from the Watson site, open a browser and type the IP address given by your router to the Amazon. You can find the IP address in the opening screen of the Watson Music app, in the device listing on your router or in Roon setup audio. It is reported with vendor name EngineerSA. You then select the update file and press Start Update. On the same page you can change the name in, for instance, Amazon Living. Be careful with non-alpha numerical characters, especially if you also want to use Airplay. But neither the update nor the name change is necessary. You can use the Amazon right out of the box. The Amazon analog is well engineered. For the sound quality it is very balanced over all specs. As a DAC it equals separate DACs in the 900 euro to 1200 euro price range. The advantage is of course that the stream rendered DAC is in the same device and thus clocked from the same crystal oscillators. That makes it easier to keep jitter low, provided the circuit board design is done well. Judging by the sound it is done very well. There are no nasties like you normally find in streamers of half the price or even more. The limitation therefore isn't inside the Amazon analog. It comes with a medical great switch mode power supply by Minwell. Although being better than a 7 euro wallward, it is low on quality compared to the Amazon on analog itself. I see this often, for instance with the SOtM streamers and I understand it. If people want to buy the Amazon for its ease of operation and care less with their ultimate sound quality, they should not pay extra for an audiophile power supply. But since I do care for sound quality, I hooked up an sBooster BOTW PMP Eco 5 Volts and that made the sound more fluent, better defined and relaxed, especially in the mid-range it sounded clearly smoother yet offered more resolution. The spaciousness increased as did the focus inside the stereo image. I can only advise anyone that care for sound quality to use an sBooster or equal power supply when buying the Amazon analog. I couldn't resist to hook up the rather sophisticated Ferron Hipsus power supply I reviewed last week. The Amazon was not in the preset list so I set it to 5 Volts and plus on the inner contact. Now the sound quality was clearly more dynamic, faster, there were deeper lows, very powerful transients and further improved pace and rhythm.  But it places the combo in the low end of my setup 1 while with the sBooster it sits in the top end of my setup 2 and with the standard power supply somewhere in the middle of setup 2. Ease of use and audio quality go hand in hand with this network renderer. Is it a network bridge, I hear you ask. Well, I like to reserve the term network bridge to devices that have digital outputs while I use network renderer for devices that have analog outputs. Both don't have internal indexing or other consoles. They need external services to send music to them as where a network player does have indexing and controls in the device itself. Watson offers both a network renderer, reviewed here and a network bridge, the Amazon Digital. Both can use the Watson Music app or equal on a smartphone or tablet and if you want to play music from your computer or NAS and not only from steaming services or internet radio, you also need a DNA or Roon server on your computer or NAS. Or use Apple Music, previously known as iTunes or other devices that can send music over Airplay, with of course the 48 kHz limitation of Airplay. You can use supplied power supply or upgrade to an audiophile power supply to further enhance the sound quality. One last remark. At first glance you might expect the Amazon Analog to be a 500 euro device. I understand that but you couldn't be further from the truth. It's worth every cent, especially when an audiophile power supply is added.  And no, I have no financial interest in power supply manufacturers. Or in Watson for that matter, but you knew that already. Which brings me to the end of this video. But know there will be a new video next Friday at 5pm central European time.

Hi, I'm Allison McFarland, Chairman of the U.S. Nuclear Regulatory Commission. The industry has been very busy in the last year. We've issued the first ever combined operating licenses for new reactors. We've also stood up a Waste Confidence Directorate in response to waste confidence decision by the courts. We have continued the work that we've been doing on the Fukushima Lessons Learned, following through on orders that we issued and considering new rules and regulations for reactor facilities. And this has been very important work. And then finally, on the international piece, we've had a number of international meetings, important international meetings, but maybe most significantly we had the first ever international conference on nuclear security that we hosted here this past November. When I came to the job, I was told by a variety of people that the staff were excellent, hardworking, dedicated, and frankly that's exactly what I found. I found an incredibly hardworking, intelligent, dedicated group of people who are really strongly interested in upholding the mission of the agency, which is ensuring public health and safety. I would like to thank them very much for all their hard work and dedication to the job here. They're serving their country, they're serving their fellow citizens, they're helping ensure that we are safe and secure in terms of our nuclear power plants, on our nuclear facilities, and nuclear materials, and I think they're doing a fantastic job. People have asked me often what surprised me most, and frankly the honest answer is going out to the reactors, meeting the resident inspectors, and seeing how really they're dedicated to the mission of the agency. That they are really separate from the licensee, they don't have lunch with them, they don't interact socially with them, they really are looking out for the best interests of the public in ensuring that the licensee is doing what they're supposed to. Well, I'm looking forward to continuing to work closely with my colleagues on the commission. I think we've established a good working relationship. Continued work on the waste confidence decision is very important, in 2013 it's very important that we keep up the momentum that we began, same with Fukushima lessons learned. We have to make sure that we keep up that momentum, that we continue to work through our tier two and tier three activities, and then finally I think it's important to really start to reach out to the public, to make sure that our internal communications are going well as well, so to pay attention to communication. I think it's important to first of all make sure that we seek public input in a variety of forms through public meetings and written communication, but that we also make a concerted effort to integrate those views into our own work. I think it's important that this be a, to the degree it can be a collaborative process with the public. And I think it's important that we continue our values, our internal values of open collaborative work environment and extend that to the outside, that we make sure that all our documents are transparent, easily accessible, easily readable, that we make sure that we ourselves are as accessible as we can be. I would like to see us move up the ladder if we can in terms of the best places to work. We're now in third place in the federal family and I'd like to see us move back up towards one and I think we need to do some homework on that and acknowledge some of the issues that were raised in the different surveys and work towards making this the best place to work in the federal government. I'm Allison McFarland and thank you for watching.

Zulzul, Zimidol, Zambla Kevin. Oh, sorry. Sorry. I'm just so fluent in similish. Sometimes I speak it by accent I think in similish as well, you know I was always useless at languages in school I studied irish for nine years and I can barely speak a word of it, but similish just comes to me naturally But today we're going to be playing the sims 2 on the psp, which is a game I played many many years ago But it's very different to normal sims. So we're going to jump in take a look at it This is going to be pretty nostalgic to me. I imagine wait so I can edit all my neighbors. This is kind of cool Have you heard of the high elves? I'm just going to make this into oblivion. Have you heard of the high elves milady tips the fedora? Oh, there he goes. He looks like he's about to drop the newest remix of lil nas old town road I'm just making everybody cowboys Probably an absolute waste of my time, but everyone is now cowboys in the village My guy looks really cool already. He even did a twirl for us. I didn't even ask him to he just did it Why is this a default face? This is no way it resembles like an actual human being. All right. What will his name be? I think his name will be milady. There we go. Yes save milady somebody please save him Oh, there he goes. Look at him. He is a protagonist He's not here looking where he's going. He's spaced looking off into the skies. He drives He's got only five dead and three in critical condition. We can only hope he's one of the dead ones What can I do that's inappropriate? Can I rob this dude? Wait, is he licking that? I don't know He just kind of went really close to it and I went Let's try and interact with another human being Oh my god, he's freaking out. I'm not just any mechanic. I'm the best mechanic. I'm an artist. Okay Like I'll I'll pay you to fix my car. I learned a secret What did I learn that this guy's fecking psychopath? Just talk to me. Don't come in here I'm trying to talk to you but you're freaking out.  You don't get out much do you? My guys want to talk. Look at them What could they possibly talk about? What could they possibly have in common? This is a weird way of socializing by the way He brings up a topic and then I have to match it and then they like that. It's weird Oh now he loves me now that I talked about Skiing and he's gonna give me a discount. All right. Go outside something like I never thought he'd do Oh, I found some trash great He just stuffed it in his pocket. It's gonna use your toilet with the door open if you don't mind It's very awkward for everyone in the shop. Oh my god. She's like doing a pam reading except You know putting her pam in my mouth I think I'm reading her pam with my tongue at least it's not the other way around because I I didn't wash my hands So I came out of the bathroom your aspiration is social you want to be popular you want everyone to love you Two of my answers were threatening people with violence if they don't do what I say She's getting pissed because I don't agree that she just defined my whole personality after sticking her hand in my mouth Well, I guess she does have a point.  I guess that's where she's coming from. Yeah, I kind of see it now I want to be rich tell her you're a fiery individual who always has to have their way. Hey, that's right Milady knows what milady wants. All right water is once change appearance. Well, that's not gonna happen Don't look at me like that. He looks right into the camera almost begging me milady Bella is running away because she was abducted by aliens. Okay. I just wanted small talk. I wanted to talk about the weather and stuff But whatever wait, what is he doing? Why is he so what are you doing dude? I already know how to flirt Clearly clearly he does call a sim. Do I have any friends?  I heard that ring and you just not answering it when you saw it was me Wake up. I want to talk to you Is this flirting is he asking? Yeah, he's asking for her number now So who was he calling on the phone a second ago acquire a home is one of my goals. Okay. What is this? Oh a phone Okay, I feel like I shouldn't answer this. Have you lost something? No, but I found this ground phone Wait, actually. Yes. I seem to have misplaced my car and my mechanic and his shop. What you should come work for me Okay. Uh, yeah, the whole garage is gone. I don't understand. It has just disappeared Oh for fuck's sake to get a ride into town. I I need to get him donuts God this trip is going really badly. I never should have left my mom's basement. All right hand over your donuts Intimidated after you just helped me learn everything about this town.   She's crying fantastic. She hides her donuts in the trash can in the restroom Okay, great. Should I tell the cop that their bathroom bin donuts or no? Yeah, I'm not gonna tell him this. I just want my ride into town. Wait. What? Oh for fuck's sake He's not taking me there until I find a place to crash All right, who can get me a house? I only know three other people and one has disappeared Along with his garage and my car and the other I just assaulted that leaves one more Bella. Hello I'm sorry. This is urgent. I had to walk in on you. I've been looking for someone to sell my house to I can't think of any place better to buy a house than a gas station restroom 900,000 simoleons. I think I have about 10 here. Will that do wait sold what I just need to give her all my money Okay, think about it an answer sure for indecisive pansies. My guy's like, that's me Well, if you're just asking for all the money in my pocket, I'm gonna spend all of my money All right. Now I have 10 bucks left. All right about that house you mentioned. Yeah, you give all the money I got it for 10 bucks. Hey stop screaming at me. It was your deal Just because I found a loophole you can't get mad. All right get in the car I think I'm getting kidnapped. No, I'm kidding. No one want to kidnap me I know that she took all of your money too. Here have some of mine. He gave me 800 dollars When I bought the place for 10. Is this my house? Oh my god. It's huge. This was the best 10 bucks I've ever spent. Wait. I have a maid Oh god, she doesn't like me. I don't blame her. This is nice. Oh, well, that's a problem right there Some ghost in his underwear is haunting the place. Oh here he is again Okay. Are you just gonna keep doing this because it's dropping my sanity meter something fierce What does she even clean? There is no furniture in here. What do I pay you for and do I pay you? I don't know. He was swimming. He turned around and then all of a sudden the ladder disappeared So I need to find his remains and bury them. God this game is weird My guy's sanity is almost nothing left And there he goes. Okay. He has lost all of his sanity. He has gone nuts. What? Oh, okay. I guess I died and went to heaven But god said you're not ready to die yet and sent me back 500 dollars. What? No, I refuse.  There's a lot of talking in this game and my guy does not like socializing He's an introvert. Look at all these cowboys God it's kind of weird that there's a graveyard in the middle of this cul-de-sac But I kind of like it.  I'm betting that these people kidnapped the the garbage man But like kind of jumping the conclusions there, buddy. Ah, this bed is just right. I don't even know these people I never introduced myself. I just walked into their house and hopped in their bed. Oh, she's showering. Hello I'd like to introduce myself. Please. This is so creepy. Hello All right, I'd like to start flirting now Wait, why didn't it work? Come on. What more does the guy gotta do? Walks into your house unannounced goes to sleep in your bed and then walks in on your showering. Hello. I've already met your wife How are you doing?  What I was just trying to access your hidden vault touch it again I'll be within my rights to set you on fire. Is this flirting again? I'm gonna touch the keypad again They do not like me. You need a logic skill of two. I have zero logic. I'm afraid I want to get in there now. I want to see what's behind there. God this sims game is weird Using their phone. I have done like everything inappropriate that I possibly can at least they're okay with me using all their furniture and Shower and everything because I have no furniture at home and there's a lot of ghosts there It's actually the house where the devil appeared and play cards and I need something for logic What can put up logic skill is bookcase. Great. Yeah, there's fine. I'm no interior designer But I know what I like and I like the bookcase here Okay, I have two things on my list now One is to get into that hidden room and the other is to find the remains of my ghost roommate All right, let's try intimidating first immediately as soon as I got into her house Yeah, that'll intimidate her. She took a step back. Anyway, that's a start There we go. I'll keep burping her face until you tell me what it is. Why is she not threatened by me? I don't understand what's not intimidating about that There you go physical violence will solve this issue. All right. She's not intimidated at all So I think I'm just gonna have to try and get my body skill up a little bit and then just Really take the battle to her or maybe a nice kick to the throat. The zombies only come out late at night What kind of neighborhood am I living in? I'm spending all my money on this to get hench The maid's probably like, uh, you still have enough money to pay me, right? Nope No, I don't I like how after a workout instead of a shower. He just washes his hands. All right Now that I'm fecking hench.  I can't wait. Oh wait. Hold on Maybe I can wait. It's time to do the zombie minigame.  This seems a bit disrespectful Okay, I lost sanity because I I didn't really do a good job, but that doesn't matter I earned 16 dollars and now I'm getting put into the insane asylum for it I mean, I did just have to beat up the dead with a shovel. I can't really blame him this time The important thing is I don't have enough money to pay for it.  Perfect sake. All right I'm gonna beat up that woman. That'll make me feel better.  I'm big and strong.   Yeah, there we go. And now can I and now can I hack this? Surely they'll be distracted with their marriage falling apart. Great. I'm getting in there. This is boring. This is just an office Oh, wait, hold on. I found the cabbage worker. God. I kind of like these neighbors now reward is that this is about well here Thank you. I I'm in serious debt. Seriously. Stop getting angry at me Honestly, I wouldn't mind being their prisoner for a while. The outside world is hard. There's zombies outside the house Just here in my tidy whiteies. You have the computer in here. Why didn't you just second email me? I'm just in there playing fortnite in their secret room. I should leave before I get locked in here My guy wants to dance. He also wants to use the toilet. Can I dance on the toilet?  Stop it. Oh my god. He's having a breakdown. I think I just died I am dead. Hello and welcome to the afterlife. I'll be your grim reaper. We have some resurrection packages available Uh, tell me about the gold package 2500 sanity points. I don't think I have any What about the bargain package? You come back with an empty stomach a full bladder and a host of other problems I mean, I'm pretty sure I died with those problems too. I'll just be a ghost for a while if that's okay All his wants are just scare someone now. This is kind of weird. There's no music or anything going on It's just me floating around silently. Wait, where's the lady? Oh, she's there. That's why he's just idling there He's waiting for her to come over but she's stuck. Okay Well, I best be leaving. I think I took their sanity along with mine. Hello everyone I'm the new neighbor. I'm dead by the way. Okay. I kept scaring all the villagers and now I can come back I just respawned right in front of him. Hey, buddy. Sorry about, you know The introduction of me being a ghost and just screaming at you.  Oh, yeah, I rescued him I forgot immediately the whole you know dying and coming back to life makes you kind of forget other things All right, the last thing I need is the remains from my roommate. Okay. This is their pool I think so it should be in here somewhere. He's kind of freaking out I am flirting with his wife got one flirt and a meter when flying up She loves what my lady has an absolutely ripped bar From working out for one day. Why do I always come in and just stare at my neighbors while they're naked? I need to get mechanical skill, but I can't afford anything to get it up There's a scratched up wedding ring lodged in hazel's drain. Okay. Well, they clearly murdered this dude And again, I respect that. Why are you having a breakdown now? He's having constant breakdown.  They're like, wait, what happened? I don't know. I was cleaning the bathroom and I just sort of died I I don't know why now. I guess I'm haunting you. Sorry. This is kind of all I got going on for me This is a great way of living to be honest by which I mean dying You just keep dying keep scaring people then come back with the gold package when you get enough points There's a note in hazel's fridge. Help. My wife is starving me to death Okay, well, that's a damning piece of evidence and I'm surprised you didn't remove it to be honest Well, you just put the food around it. Oh my god. What's happening to you now? You're starving to death Why is there always something wrong with you? Okay? I'm dead again. Yeah, just keep scaring keep scaring All right. Sorry about scaring you and all that dude, but I'm glad to be back and sane as ever Which is not very you found a pacemaker buried in her garden.
