Abstract:
A semiconductor apparatus comprising:an impurity diffusion layer of a drain and source of a MISFET selectively formed on the surface of a semiconductor substrate or a semiconductor layer;a gate electrode formed on a channel region between the drain and the source through a gate insulating film;a side-wall insulating film formed on the side wall of the gate electrode;an interlayer insulating film formed to cover the gate electrode and the side-wall insulating film and having an opened portion including a side-portion removed region obtained by removing a portion of the side portion of the side-wall insulating film on an impurity diffusion layer for the drain and source;a silicide compound layer formed on the impurity diffusion layer for the drain and source, the silicide compound layer being formed on the bottom surface of the opening of the interlayer insulating film corresponding to the side-portion removed region; anda conductor formed in the opening and made contact with the silicide compound layer.
