Patent ID: 7115956

Claim:
A semiconductor device, comprising: a semiconductor layer comprising a source region, a drain region, and a channel region; a gate insulating film over the semiconductor layer; at least two island-like conductive films over the gate insulating film; a source wiring formed between the at least two island-like conductive films, over the gate insulating film; an insulating film over the source wiring and the at least two island-like conductive films; and first and second connection wirings over the insulating film, wherein the source wiring is electronically connected to the source region through the first connection wiring, wherein the first and second connection wirings comprise the same material wherein one of the at least two island-like conductive films overlaps with the channel region through the gate insulating film, and wherein the at least two island-like conductive films are electrically connected to each other through the second connection wiring.
