    摘要: Provided is a method of fabricating a semiconductor device including a high-k metal gate structure. A substrate is provided including a dummy gate structure (e.g., a sacrificial polysilicon gate), a first and second hard mask layer overlie the dummy gate structure. In one embodiment, a strained region is formed on the substrate. After forming the strained region, the second hard mask layer may be removed. A source/drain region may be formed. An ILD layer is then formed on the substrate. A CMP process may planarize the ILD layer using the first hard mask layer as a stop layer. The CMP process may be continued to remove the first hard mask layer. The dummy gate structure is then removed and a metal gate provided.
