Claim:
1. A semiconductor device including a MISFET; said semiconductor device comprising: a first film that covers an entirety of said MISFET; said first film being of a film thickness thinner than the height of a gate electrode and consisting of a single layer of a same material; and a second film arranged on said first film; wherein said first film and said second film are films subjected to compressive stress; a compressive stress of said first film is lower than that of said second film; and gate sidewall spacers arranged on both sides of said gate electrode; said gate sidewall spacers being of a cross-sectional shape of an uppercase letter L, wherein said gate sidewall spacers with cross-sectional shape of an uppercase letter L directly contact said first film along an entirety of side of said gate sidewall spacers opposite said gate electrode.
