ABSTRACT:
Disclosed is an insulated gate semiconductor device including a first region having a gate electrode region and a first insulating film region surrounding the gate electrode region; a semiconductor region which includes a channel forming region and is disposed to oppose the gate electrode region with the first insulating film region between them; and a second region which has a conductor region buried in a semiconductor region not including the channel forming region disposed to oppose the gate electrode region with the first insulating film region between them, and has a second insulating film region which separates the conductor region from the semiconductor region.
