Abstract:
1. A method of fabricating a semiconductor device, comprising the steps of: forming, on a substrate including a device region by a device isolation region, a field effect transistor in corresponding to said device region, such that a polysilicon pattern extends out from a polysilicon gate electrode of said field effect transistor, such that said polysilicon pattern extends over said device isolation region; depositing a metal film on said substrate so as to cover said gate electrode and said polysilicon pattern; forming a mask pattern on said metal film so as to cover a part of said polysilicon pattern existing on said device isolation region; etching said metal film while using said mask pattern as a mask so as to reduce a thickness of said metal film in a part thereof not covered with said mask pattern; and forming a silicide layer on a surface of said gate electrode and a surface of said polysilicon pattern by applying an annealing process after removing said mask pattern.
