Patent ID: 7224034

Claim:
A semiconductor integrated circuit device, comprising: (a) a semiconductor substrate having a main surface; (b) a first insulating film formed on the main surface of the semiconductor substrate; (c) a silicon film formed on the first insulating film, which has a first sidewall positioned adjacent to the first insulating film and a second sidewall positioned apart from the first insulating film; (d) a refractory metal film formed above the silicon film and having a third sidewall; and (e) a second insulating film formed on the second and third sidewalls; and (f) a third insulating film formed on the first sidewall, wherein the third insulating film has a first portion positioned between the first and second insulating films and a second portion positioned between the first portion and the silicon film, wherein an upper end of the second portion of the third insulating film is higher than that of the first portion of the third insulating film, and wherein a part of the silicon film is interposed between the second portion of the third insulating film and the refractory metal film.
