[Patent application number] 20100133531 [Published] 06-03-2010 [Description] 
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF - A gate electrode layer over a substrate; a gate insulating layer over the gate electrode layer; a first source electrode layer and a first drain electrode layer over the gate insulating layer; an oxide semiconductor layer over the gate insulating layer; and a second source electrode layer and a second drain electrode layer over the oxide semiconductor layer. A first part, a second part, and a third part of a bottom surface are in contact with the first source electrode layer, the first drain electrode layer, and the gate insulating layer respectively. A first part and a second part of the top surface are in contact with the second source electrode layer and the second drain electrode layer respectively. The first source electrode layer and the first drain electrode layer are electrically connected to the second source electrode layer and the second drain electrode layer respectively.
