摘要:
A method to fabricate a semiconductor device includes forming a semiconductor fin on a substrate; forming a dummy gate material layer over the semiconductor fin; forming a contact hole in the dummy gate material layer; forming a source/drain feature in the contact hole; forming a contact feature on the source/drain feature within the contact hole; and replacing a dummy gate that is formed of the dummy gate material layer with a metal gate.
