ABSTRACT:
An electrode on a semiconductor substrate includes a polysilicon layer, a silicon-implanted layer on the polysilicon layer, a tungsten nitride layer on the silicon-implanted layer, a tungsten nitride layer on the silicon-implanted layer, and a tungsten layer on the tungsten nitride layer. The layer between the polysilicon layer and the tungsten nitride layer may be either a tungsten silicon nitride layer or a silicon-germanium layer.
