METAL OXIDE SEMICONDUCTOR TRANSISTOR

摘要

A metal oxide semiconductor (MOS) transistor is disclosed. The MOS transistor includes: a semiconductor substrate; a gate disposed on the semiconductor substrate, wherein the gate comprises two sidewalls; a spacer formed on the sidewalls of the gate; a source/drain region disposed in the semiconductor substrate; a silicide layer disposed on top of the gate and the surface of the source/drain region; and a retarded interface layer disposed in the junction between the silicide layer and the gate and source/drain region.
