Patent ID: 7176526

Claim:
A semiconductor device comprising a semiconductor substrate and a plurality of field effect transistors provided on the semiconductor substrate, wherein: each of the plurality of field effect transistors comprises: a gate electrode provided on the semiconductor substrate; a gate electrode side wall insulating film provided at a side of the gate electrode; and a conductive film to be a source region or a drain region, provided at a side of the gate electrode via the gate electrode side wall insulating film; wherein the gate electrode of each of the plurality of field effect transistors is produced by the step of dividing a first non-insulating film into a plurality of regions; the conductive film of each of the plurality of field effect transistors is produced by the step of dividing a second non-insulating film into a plurality of regions; and in a region extending from the gate electrode of each of the plurality of field effect transistors to the respective gate electrode of a neighboring field effect transistor the gate electrode side wall insulating film is not formed.
