Abstract:
Gate stacks for improving integrated circuit device performance and methods for fabricating such gate stacks are disclosed herein. An exemplary method includes forming a gate stack over a substrate and at least partially removing the gate stack, thereby forming an opening. A multi-function layer is deposited in the opening and a work function layer is deposited over the multi-function layer. The multi-function layer includes nitrogen and one of titanium or tantalum. The work function layer includes nitrogen and one of titanium or tantalum. A concentration of the nitrogen of the work function layer is different than a concentration of the nitrogen of the multi-function layer. In some implementations, the concentration of the nitrogen of the work function layer from about 2% to about 5% and the concentration of the nitrogen of the multi-function layer from about 5% to about 15%.

Claim (Index 10):
The method of  claim 9 , wherein the depositing the multi-function layer and the depositing the work function layer includes performing a physical vapor deposition process that implements a precursor that includes nitrogen and one of titanium or tantalum, wherein the physical vapor deposition process is tuned to set the concentration of the nitrogen of the work function layer from about 2% to about 5% and the concentration of the nitrogen of the multi-function layer from about 5% to about 15%.
