Abstract:
A semiconductor device and method of manufacturing are provided. In an embodiment a first nucleation layer is formed within an opening for a gate-last process. The first nucleation layer is treated in order to remove undesired oxygen by exposing the first nucleation layer to a precursor that reacts with the oxygen to form a gas. A second nucleation layer is then formed, and a remainder of the opening is filled with a bulk conductive material.

Claim (Index 16):
A transistor comprising:\n a first source/drain region; a second source/drain region; and a gate disposed between the first source/drain region and the second source/drain region, the gate comprising:\n a gate dielectric; \n one or more work function metal layers over the gate dielectric; \n a barrier layer over the one or more work function metal layers; \n a plurality of tungsten-comprising layers over the barrier layer, an oxygen concentration at an interface between a first one of the plurality of tungsten-comprising layers and a second one of the plurality of tungsten-comprising layers is greater than zero but less than 0.1% atomic; and \n a metal layer over the plurality of tungsten-comprising layers.
