Abstract:
A method of forming a semiconductor device includes forming a gate dielectric layer on a substrate; forming a barrier layer over the gate dielectric layer; treating the barrier layer to roughen an outer surface of the barrier layer, resulting in a treated barrier layer; and forming a metal layer over the treated barrier layer.

Claim (Index 20):
The semiconductor structure of  claim 19 , further comprising a capping layer between the first gate dielectric layer and the first barrier layer, wherein each of the n-type work function metal layer and the first barrier layer includes aluminum, and wherein the first gate stack also includes aluminum between the first barrier layer and the capping layer.
