Method of eliminating edge effect in chemical vapor deposition of a metal

摘要

A method of eliminating an edge effect in chemical vapor deposition of a metal such as copper on a semiconductor substrate surface. A susceptor in a reaction chamber is exposed to a plasma. A substrate contained thereon and processed by chemical vapor deposition has a uniform metal layer at edge and non-edge surfaces. A plurality of substrates may be processed before reexposing the susceptor to the plasma.
