Patent ID: 8115278

Claim:
A semiconductor device comprising: a first insulating film over a substrate; an island-shaped semiconductor film having an impurity region over the first insulating film, the impurity region comprising: a first region over the first insulating film; and a second region over the first region; a second insulating film, which is over the island-shaped semiconductor film, formed so as to expose a portion of the impurity region; a first electrode and a second electrode separated in a direction over the second insulating film, wherein the first electrode and the second electrode overlap the island-shaped semiconductor film so that a first channel formation region and a second channel formation region are formed in the impurity region, and wherein the first electrode and the second electrode are aligned along a channel width direction of the first channel formation region; a first insulator on a first side face of each of the first electrode and the second electrode, and a second insulator in a region between a second side face of the first electrode and a second side face of the second electrode, and a resistive element formed in the impurity region between the first channel formation region and the second channel formation region, wherein a metal silicide is formed in the second region.
