201100:00 berndjazonenberg, i don't get why *high*-k dielectrics
are good for gate insulation.  doesn't that increase the gate
capacitance?17:03 azonenbergberndj: but it also decreases
leakage17:45 azonenbergi think17:45 azonenbergand lets you make
the dielectric thinner17:45 azonenbergby contrast you want low-K
for ILD17:46 azonenbergso you dont have capacitive coupling
between wires etc17:46 azonenbergor wire capacitance getting in
the way as much17:46 azonenbergberndj: i think it also lets you
make the gate smaller17:49 azonenberginter-layer dielectric17:50
berndjokay so it's more like it *happens* to have high-K, but
that isn't the reason you use it for gate insulation: instead
you're using it for the higher dielectric strength it also
has?17:51 azonenbergThey're the same thing17:51 azonenberghigher
dielectric strength will increase capacitance17:51 berndjerr,
correlated, i'm sure, but not the same thing?17:51 azonenbergAnd
doing a little bit of rea
