Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first insulating film over a metal substrate; forming a semiconductor layer over the first insulating film; forming a second insulating film over the semiconductor layer and the first insulating film; forming a gate electrode over the second insulating film; removing a portion of the second insulating film, so as to expose a portion of the first insulating film; forming a third insulating film over the gate electrode and the second insulating film and contacting the portion of the first insulating film; partly removing the third insulating film so as to expose the portion of the first insulating film; and forming a wiring line electrically connected to the semiconductor layer and in contact with the portion of said first insulating film, wherein a storage capacitor is formed of the metal substrate and the wiring line, with the portion of the first insulating film therebetween.
