Patent ID: 7348627

Claim:
A semiconductor device comprising: a semiconductor layer; a first insulating film formed on said semiconductor layer; a first electrode layer formed on said first insulating layer; an element isolating region including an element isolating insulating film formed to extend through said first electrode layer and said first insulating film to reach an inner region of said semiconductor layer, said element isolating region isolating an element region and being self-aligned with said first electrode layer; a second insulating film formed on said first electrode layer and said element isolating region, first and second open portions exposing surfaces of said first electrode layer being formed in said second insulating film, widths of the first and second open portions being equal to each other; and a second electrode layer formed above said second insulating film and said exposed surfaces of said first electrode layer, said second electrode layer being electrically connected to said first electrode layer via said first and second open portions.
