Abstract:
1. A semiconductor device comprising: a first electrode provided above a surface of a semiconductor substrate with a first insulating film interposed between said first electrode and said semiconductor substrate; a charge accumulation film formed beside said first electrode on the surface of said semiconductor substrate; a second electrode provided on a surface of said charge accumulation film; a sidewall insulating film provided beside said second electrode, wherein said second electrode is formed such that a surface facing to said first electrode is substantially parallel with a surface facing to said sidewall insulating film in a sectional shape thereof, and said second electrode is formed such that a top face is recessed to form a substantially V-shaped in the sectional shape thereof; a first silicide film provided on an upper surface of said first electrode; and a second silicide film formed such that a top surface is recessed to form a substantially V-shaped in the sectional shape thereof on said top face of said second electrode.
