Patent ID: 7109071

Claim:
A method of manufacturing a semiconductor device comprising: forming a first insulating film over a first substrate; forming at least first and second thin film transistors over the first insulating film; forming a second insulating film over the first and second thin film transistors; forming a wiring and a first electrode over the second insulating film, wherein the wiring is connected to the first thin film transistor through a first contact hole in the second insulating film, and the first electrode is connected to the second thin film transistor through a second contact hole in the second insulating film; forming a third insulating film over the second insulating film, the wiring, and the first electrode; forming a third contact hole for reaching the first electrode in the third insulating film; bonding a second substrate to a surface of the third insulating film; removing the first substrate; forming a fourth contact hole for reaching the first thin film transistor in the first insulating film; forming a second electrode on the first insulating film, wherein the second electrode is connected to the first thin film transistor through the fourth contact hole; forming a fourth insulating film over the first insulating film and the second electrode; and forming a fifth contact hole for reaching the second electrode in the fourth insulating film; and removing the second substrate.
