Abstract
A semiconductor device is formed in a semiconductor layer. A gate stack is formed over the semiconductor layer and comprises a first conductive layer and a second layer over the first layer. The first layer is more conductive and provides more stopping power to an implant than the second layer. A species is implanted into the second layer. Source/drain regions are formed in the semiconductor layer on opposing sides of the gate stack. The gate stack is heated after the step of implanting to cause the gate stack to exert stress in the semiconductor layer in a region under the gate stack.
