Abstract
A semiconductor device manufacturing method wherein a metal suicide layer is formed via an in-situ process. The method includes forming a gate electrode on a semiconductor substrate; forming an insulation side wall at either lateral surface of the gate electrode; forming a source/drain region in a surface of the semiconductor substrate at either side of the gate electrode; forming a metal layer on the surface of the semiconductor substrate including the gate electrode; performing a plasma treatment on the metal layer; forming a capping material layer on the metal layer; performing an annealing process upon the semiconductor substrate, to form a metal silicide layer on the surface of the semiconductor substrate at positions corresponding to the gate electrode and the source/drain region; and removing the capping material layer and the metal layer remained without reaction with the gate electrode and the semiconductor substrate.
