Patent ID: 7994586

Claim:
A semiconductor device comprising: a p-channel type transistor in a semiconductor region, the p-channel type transistor comprising: a gate electrode formed above the semiconductor region; a silicide layer formed above the gate electrode; a sidewall insulation film formed over both side surfaces of the gate electrode; a pair of p-type impurity diffusion regions formed in both sides of the gate electrode; and a tensile stress insulation film formed to cover at least the gate electrode and the sidewall insulation film, wherein the sidewall insulation film has an inside sidewall insulation film formed inside and an outside sidewall insulation film formed outside to cover at least part of the inside sidewall insulation film, and wherein the upper surface of the silicide layer is lower than an upper portion of the outside sidewall insulation film and an upper portion of the inside sidewall insulation film is lower than the upper portion of the gate electrode.
