Abstract:
A method is provided for making a semiconductor device. In accordance with the method, a substrate (203) is provided which has first (205) and second (207) gate structures thereon. A first stressor layer (215) is formed over the substrate, and a sacrificial layer (216) is formed over the first stressor layer. A second stressor layer (219) is formed over the sacrificial layer.
