Abstract:
1. A semiconductor device comprising: a semiconductor substrate including a source region and drain region at its surface; a gate electrode formed so as to include a straight portion separating said source region and said drain region on said semiconductor substrate; a dummy electrode formed at a position on an extension of a longitudinal axis of said gate electrode; a stopper insulating film, each overlying said gate electrode and said dummy electrode; a sidewall insulating film covering a side of said gate electrode, said dummy electrode and said stopper insulating film; an interlayer insulating film formed on said semiconductor substrate to cover up said sidewall insulating film and said stopper insulating film; and a linear contact portion defined by a conductive member extending vertically in said interlayer insulating film and electrically connected to one of said source region and said drain region at its bottom end, said linear contact portion extending parallel to said straight portion of said gate electrode, said linear contact portion extending to above said dummy electrode; wherein a gap between said gate electrode and said dummy electrode is filled with said sidewall insulating film.
