Patent ID: 7408193

Claim:
A semiconductor device comprising: a first thin film device; a second thin film device formed over the first thin film device; a third thin film device formed over the second thin film device, each of the first, second, and third thin film devices comprising: a first insulating film; a first electrode formed over the first insulating film; a second insulating film formed over the first electrode; first and second thin film transistors formed over the second insulating film, wherein the first thin film transistor is connected to the first electrode through a first contact hole; a third insulating film formed over the first and second thin film transistor; a second electrode formed over the third insulating film, wherein the second electrode is connected to the second thin film transistor through a second contact hole; and a fourth insulating film formed over the third insulating film and the second electrode, wherein the second electrode of the first thin film device is electrically connected to the first electrode of the second thin film device, and wherein the second electrode of the second thin film device is electrically connected to the first electrode of the third thin film device.
