Abstract:
A system for providing a pre-deposition treatment (e.g., of a work-function layer) to accomplish work function tuning. In various embodiments, a gate dielectric layer is formed over a substrate, and a work-function metal layer is deposited over the gate dielectric layer. In some embodiments, a first in-situ process including a pre-treatment process of the work-function metal layer is performed. By way of example, the pre-treatment process removes an oxidized layer of the work-function metal layer to form a treated work-function metal layer. In some embodiments, after performing the first in-situ process, a second in-situ process including a deposition process of another metal layer over the treated work-function metal layer is performed.

Claim (Index 20):
The method of  claim 15 , wherein the pre-treatment process removes an oxidized layer from a top surface of the work-function metal layer.
