Abstract

Provided is a semiconductor device including a substrate, a gate insulating film which is formed on the substrate, and a gate electrode which is provided on the gate insulating film. The gate electrode includes a first metal silicide including a first metal material, and a second metal silicide including one of a second metal material and the second metal material in a contact portion between the gate insulating film and the gate electrode. The second metal silicide including the second metal material is a metal-rich silicide in which the composition ratio of the second metal material to silicon in the second metal silicide including the second metal is greater than 1.
