    摘要: A support ring for semiconductor processing is provided. The support ring includes a ring shaped body defined by an inner edge and an outer edge. The inner edge and outer edge are concentric about a central axis. The ring shaped body further includes a first side, a second side, and a raised annular shoulder extending from the first side of the ring shaped body at the inner edge. The support ring also includes a coating on the first side. The coating has an inner region of reduced thickness region abutting the raised annular shoulder.
