Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first wiring on a substrate having an insulating surface; forming a first insulating film on the first wiring; forming a semiconductor film on the first wiring; forming a second insulating film on the semiconductor film; forming a first contact hole reaching the first wiring by selectively etching the first insulating film and the second insulating film; forming a gate electrode on the second insulating film, wherein the gate electrode is electrically connected to the first wiring through the first contact hole; forming a third insulating film on the gate electrode; forming a second contact hole reaching the semiconductor film by selectively etching the second insulating film and the third insulating film; and forming a third wiring on the third insulating film, wherein the third wiring is electrically connected to the semiconductor film through the second contact hole.
