Abstract:
A sequential plasma process is employed to enable the modification of the work function of a p-type metal layer in a metal gate structure. The sequential plasma process includes a plasma hydrogenation and a plasma process that includes electronegative species. The sequential plasma process is performed on a p-type metal layer in a film stack, thereby replacing suboxides and/or other non-stoichiometrically combined electronegative atoms disposed on or within layers of the film stack with stoichiometrically combined electronegative atoms, such as O atoms. As a result, the work function of the p-type metal layer can be modified without changing a thickness of the p-type metal layer.

Claim (Index 14):
The method of  claim 11 , wherein the exposed surface is not exposed to air after being exposed to the plasma-excited hydrogen species and before being exposed to the plasma-excited electronegative species.
