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 8):
A semiconductor device comprising:\n a semiconductor fin; a high-k dielectric liner along a top surface and sidewalls of the semiconductor fin; and a gate electrode over the high-k dielectric liner, wherein the gate electrode is disposed along a top surface and sidewalls of the semiconductor fin, and wherein the gate electrode comprises:\n a first metal-comprising material; \n a second metal-comprising material over the first metal-comprising material, the second metal-comprising material having a different material composition than the first metal-comprising material; \n a first nucleation layer over the second metal-comprising material; and \n a second nucleation layer over and forming an interface with the first nucleation layer, wherein an oxygen concentration at the interface between the first nucleation layer and the second nucleation layer is greater than zero but less than 0.1% atomic; and \n a third metal-comprising material over the second nucleation layer, wherein the third metal-comprising material extends continuously from a first sidewall of the second nucleation layer to a second sidewall of the second nucleation layer.
