Patent ID: 7880306

Claim:
A semiconductor device comprising: a semiconductor substrate having a main surface; an element separation film formed on the main surface in an element separation area, said element separation film extending in a first direction; a semiconductor element formed on the main surface in an. active area and arranged in a second direction perpendicular to the first direction, said semiconductor element including a metal silicide film, said metal silicide film including a first portion adjacent to the element separation film, said metal silicide film further including a second portion away from the element separation film, said second portion having a thickness smaller than that of the first portion; an interlayer insulation film formed on the main surface; a wiring portion formed on the interlayer insulation film; and a conductive plug formed in the interlayer insulation film for electrically connecting the semiconductor elements and the wiring portion, said conductive plug being situated on the element separation film and the metal silicide film.
