摘要:
The invention improves the performance of a semiconductor device. A metal silicide film is formed by a silicide process on a gate electrode and an n+-type source region of an LDMOSFET, and no such metal silicide film is formed on an n−-type offset drain region, an n-type offset drain region, and an n+-type drain region. A side wall spacer comprising a silicon film is formed via an insulating film on the side wall of the gate electrode over the drain side thereof, and a field plate electrode is formed by this side wall spacer. The field plate electrode does not extend above the gate electrode, and a metal silicide film is formed over the entire upper surface of the gate electrode in the silicide process.
