Abstract:
1. A semiconductor device comprising: a gate electrode over an insulating surface; a gate insulating film over the gate electrode; a semiconductor film over the gate insulating film; a first insulating film over the semiconductor film, the first insulating film having an opening; a first conductive film over the first insulating film, the first conductive film being in contact with the semiconductor film through the opening of the first insulating film; a second insulating film over the first conductive film, the second insulating film being in contact with side surfaces of the gate electrode, the gate insulating film, the semiconductor film, the first insulating film and the first conductive film, the second insulating film having an opening; and a second conductive film over the second insulating film, the second conductive film being in contact with the first conductive film through the opening of the second insulating film, wherein outer circumferences of the gate electrode, the gate insulating film, and the semiconductor film are substantially aligned.
