Patent ID: 7750347

Claim:
A semiconductor device including a memory, the memory comprising: a semiconductor island formed over an insulating transparent substrate; a source region and a drain region provided in the semiconductor island; a channel region provided between the source region and the drain region in the semiconductor island; a gate insulating film formed on the semiconductor island; a floating gate over the channel region of the semiconductor island with the gate insulating film therebetween; an insulating layer covering the floating gate wherein said insulating layer comprises a metal oxide; a control gate over the floating gate with the insulating layer therebetween; a first electrode connected to the source region and provided over the insulating layer; and a second electrode connected to the drain region and provided over the insulating layer, wherein the control gate and the first electrode and the second electrode are provided in a same conductive layer, and wherein the control gate is connected to a wiring provided in a layer same as the floating gate.
