Patent ID: 8004046

Claim:
A semiconductor device, comprising: a gate insulating film formed on a first semiconductor region and a second semiconductor region which have different conductivity types; a first gate electrode including a first conductive film formed on the gate insulating film in the first semiconductor region; a second gate electrode including a first metal film and a second conductive film made of silicon that are successively formed on the gate insulating film in the second semiconductor region; an insulating film formed in the first semiconductor region and the second semiconductor region so as to cover the gate electrode; and a second metal film extending through the insulating film, and connected to the first metal film, wherein the first metal film has a vertical portion protruding upwardly and vertically to the second semiconductor region in a portion of the second semiconductor region to be adjacent to the first semiconductor region, an upper end surface of the vertical portion of the first metal film is exposed from the first conductive film and the second conductive film, and the second metal film is connected to the upper end surface of the vertical portion of the first metal film.
