摘要:
In one aspect, a method for forming a semiconductor device includes forming a stressor layer over a gate stack and a spacer adjacent the gate stack, implanting a species into at least a portion of the stressor layer, and curing the stressor layer. In another aspect, a method includes forming an etch stop layer over a semiconductor substrate, where the etch stop layer has a structure, modifying at least a portion of the structure of the etch stop layer, and curing the etch stop layer after modifying at least the portion of the structure of the etch stop layer.
