Patent ID: 7612402

Claim:
A semiconductor device comprising: a nonvolatile memory cell formed on a semiconductor substrate and having a first gate electrode including a first portion of a first conductive film, and a resistance element being formed on the semiconductor substrate and having a second portion of the first conductive film, wherein the nonvolatile memory cell has: first portions of a first insulating film formed over sidewalls of the first gate electrode, first semiconductor regions formed in the semiconductor substrate, first portions of a silicide layer formed over the first semiconductor regions, first portions of a second insulating film covering an area over the first gate electrode and the first portions of the first insulating film, and a third insulating film formed so as to cover the first portions of the silicide layer and the first portions of the second insulating film; and the resistance element has: second portions of the first insulating film formed over sidewalls of the second portion of the first conductive film, second portions of the second insulating film covering an area over the second portion of the first conductive film and over the second portions of the first insulating film, and having an opening on a part of the second portion of the first conductive film, and a second portion of the silicide layer formed on the part of the second portion of the first conductive film in the opening, wherein the third insulating film covers the second portions of the first insulating film, the second portions of the second insulating film, and the second portion of the silicide layer.
