摘要： A hard mask may be formed and maintained over a polysilicon gate structure in a metal gate replacement technology. The maintenance of the hard mask, such as a nitride hard mask, may protect the polysilicon gate structure 14 from the formation of silicide or etch byproducts. Either the silicide or the etch byproducts or their combination may block the ensuing polysilicon etch which is needed to remove the polysilicon gate structure and to thereafter replace it with an appropriate metal gate technology.

摘要： A complementary metal oxide semiconductor integrated circuit may be formed with a PMOS device formed using a replacement metal gate and a raised source drain. The raised source drain may be formed of epitaxially deposited silicon germanium material that is doped p-type. The replacement metal gate process results in a metal gate electrode and may involve the removal of a nitride etch stop layer.
