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 1):
A method comprising:\n depositing a dielectric layer over a substrate; depositing a first work function metal layer over the dielectric layer; depositing a dummy layer over the first work function metal layer; introducing an impurity into the first work function metal layer, comprising:\n depositing a work function adjusting layer over the dummy layer; \n removing the work function adjusting layer; removing the dummy layer after the work function adjusting layer is removed; and depositing a second work function metal layer over the first work function metal layer.
