Patent ID: 8859368

Claim:
A method of forming a semiconductor device, comprising: applying a high-k dielectric layer and a work function (WF) layer over a p-FET portion and an n-FET portion of the device; removing the WF layer from over the n-FET portion; recessing the high-k dielectric layer and the WF layer over the p-FET portion and recessing the high-k dielectric layer over the n-FET portion; applying a multi-function layer over the p-FET portion and the n-FET portion; recessing the multi-function layer over the p-FET portion, resulting in exposure of a Portion of the high-k dielectric layer and a portion of the WF layer over the p-FET portion; recessing the multifunction layer over the n-FET portion, resulting in exposure of the high-k dielectric layer over the n-FET portion; and applying a cap layer into direct contact with the portion of the WF layer, the portion of the high-k dielectric layer, and a portion of the multi-function layer over the p-FET portion.
