Abstract
A semiconductor structure and method for making the same provides a gate dielectric formed of oxynitride or a nitride/oxide stack formed within a recess. Amorphous silicon is deposited on the gate dielectric within the recess and a metal is deposited on the amorphous silicon. An annealing process forms a metal silicide gate within the recess on the gate dielectric. A wider range of metal materials can be selected because the gate dielectric formed of oxynitride or a nitride/oxide stack remains stable during the silicidation process. The metal silicide gate significantly reduces the sheet resistance between the gate and gate terminal.
