Abstract:
A method is provided. The method includes the following operations. A dielectric layer is deposited over a substrate. Then, a first work function metal layer is deposited over the dielectric layer. Next, a dummy layer is deposited over the first work function metal layer. Afterwards, an impurity is introduced into the first work function metal layer. Then, the dummy layer is etched. Next, a second work function metal layer is deposited over the first work function metal layer.

Claim (Index 11):
The method of  claim 1 , wherein introducing the impurity into the first work function metal layer further comprises:\n annealing the work function adjusting layer to diffuse the impurity into at least one of the dummy layer and the first work function metal layer prior to removing the work function adjusting layer.
