Patent ID: 7242021

Claim:
A semiconductor device comprising: an active layer; a gate insulating film over the active layer; a gate electrode over the active layer with the gate insulating film interposed therebetween; a first inorganic insulating film formed over the active layer; an SOG film formed over the first inorganic insulating film, said SOG film having a first opening; a second inorganic insulating film formed over the SOG film; and a wiring formed over the second inorganic insulating film; wherein an inner wall surface of the first opening is covered with the second inorganic insulating film, wherein said SOG film comprises silicon oxide, wherein a second opening formed in a laminated body including the gate insulating film, the first inorganic insulating film and the second inorganic insulating film is provided to the inside of the first opening, and wherein the active layer and the wiring are connected to each other through the first opening and the second opening.
