摘要:
Methods, apparatus, and systems are provided for retaining a substrate in a polishing head of a CMP system. The invention includes a flexible inner retaining ring adapted to contour to an edge of a substrate and an inner ring support coupled to the polishing head. The inner support ring is adapted to contact the flexible inner retaining ring in response to a side force load applied to the flexible inner retaining ring by a substrate being polished. Numerous additional aspects are disclosed.
