摘要:
A sacrificial gate structure, including nitride and fill layers, may be replaced with a metal gate electrode. The metal gate electrode may again be covered with a nitride layer covered by a fill layer. The replacement of the nitride and fill layers may reintroduce strain and provide an etch stop.
