The transistors can be formed from a metal silicon compound deficient of silicon bonding atoms on a dielectric material overlying a semiconductor substrate conductively doped for PMOS and NMOS regions. The metal silicon compound overlying the NMOS region is converted to a metal silicon nitride and the metal silicon compound overlying the PMOS region is converted to a metal silicide. NMOS transistor gate electrodes comprising metal silicon nitride and PMOS transistor gate electrodes comprising metal silicide can be formed.

Abstract: A method used to form a semiconductor device comprises forming a polysilicon layer, forming a conductive barrier layer on the polysilicon layer, then forming a conductive nitride layer on the conductive barrier layer. Next, a conductive amorphous layer is formed on the conductive barrier layer, and an elemental metal layer is formed on the conductive amorphous layer. Without the conductive amorphous layer the elemental metal layer would form on the conductive nitride layer as a small grained, high resistance layer, while it forms on the conductive amorphous layer as a large grained, low resistance layer. A semiconductor device which may be formed using this method is also described.
