ABSTRACT:
A tungsten nitride (6b) is provided also on side surface of a tungsten (6c), to increase an area where the tungsten (6c) and the tungsten nitride (6b) are in contact with each other. On a gate insulating film (2), a polysilicon side wall (5) having high adhesive strength to the gate insulating film is disposed. The polysilicon side wall (5) is brought into a close contact with the tungsten nitride (6b) on the side surface of the tungsten (6c). With this structure improved is adhesive strength of a metal wire or a metal electrode which is formed on an insulating film of a semiconductor device.
