| Zusammenfassung: | A semiconductor device comprises: a semiconductor substrate; a gate insulating film formed on the top surface of the semiconductor substrate; a gate electrode formed on the gate insulating film; diffusion layers formed in the semiconductor substrate to be used a source layer and a drain layer; and a silicide layer formed to overlie the diffusion layers; wherein an oxygen concentration peak, where oxygen concentration is maximized, is at a level lower than said top surface in a cross-section taken along a plane perpendicular to said top surface. |
