摘要: A structure and method for replacement metal gate (RMG) field effect transistors is disclosed. Silicide regions are formed on a raised source-drain (RSD) structure. The silicide regions form a chemical mechanical polish (CMP) stopping layer during a CMP process used to expose the gates prior to replacement. Protective layers are then applied and etched in the formation of metal contacts.
