Patent ID: 8067793

Claim:
A semiconductor device comprising: a first insulating layer; a second insulating layer over the first insulating layer; a lower electrode of a storage capacitor portion over a first portion of the second insulating layer; an insulating film of the storage capacitor portion formed over and in contact with a surface of the lower electrode of the storage capacitor portion, the insulating film of the storage capacitor portion including at least yttrium oxide; an island-like single crystal silicon layer over a second portion of the second insulating layer, the island-like single crystal silicon layer comprising a channel forming region and impurity regions; a gate electrode over the island-like single crystal silicon layer with a gate insulating film interposed therebetween; an interlayer insulating film covering the island-like single crystal silicon layer, the gate insulating film, the gate electrode, and the lower electrode of the storage capacitor portion; and a wiring over the interlayer insulating film, wherein the wiring is in contact with the insulating film of the storage capacitor portion, and wherein the lower electrode and the insulating film of the storage capacitor portion are embedded in the second insulating layer.
