Patent ID: 6955953

Claim:
A method of fabricating a semiconductor device comprises steps of: forming an active layer over a substrate; forming an insulating film containing silicon on said active layer; exposing a portion of said active layer by removing a part of said insulating film containing silicon; forming a first insulating film over the exposed portion of said active layer; forming a gate wiring and a second capacitance electrode over said insulating film containing silicon and said first insulating film; forming a first interlayer insulating film over said gate wiring and said second capacitance electrode; exposing a portion of said second capacitance electrode by removing a part of said first interlayer insulating film; forming a second dielectric over the exposed portion of said second capacitance electrode; forming a light-shielding film over said first interlayer insulating film and said second dielectric; forming a second interlayer insulating film over said light-shielding film; forming a source wiring or a drain wiring over said second interlayer insulating film; forming a third interlayer insulating film over said source wiring or said drain wiring; and forming a pixel electrode, over said third interlayer insulating film, electrically connected with said light-shielding film and said drain wiring.
