Abstract:
1. A semiconductor device, comprising: a substrate; a gate electrode provided on said substrate; a diffusion region formed in said substrate adjacent to said gate electrode; a side-wall insulation film formed on a side wall of said gate electrode; a self-aligned contact hole defined by said side-wall oxide film and exposing said diffusion region; and a silicide region formed selectively on a surface of said diffusion region; wherein said semiconductor device further includes; a first insulation film provided on said gate electrode so as to cover said side wall oxide film partially; a second insulation film having a composition different from a composition of said first insulation film and provided on said first insulation film; an interlayer insulation film deposited on said second insulation film; a contact hole formed in said interlayer insulation film, said contact hole extending through said first and second insulation films and exposing said self-aligned contact hole; said first insulation film contains H
