A chemical mechanical polishing apparatus including a carrier head having an integral conditioning member is described. The conditioning member includes a conditioning surface that may selectively be moved into contact with a polishing surface of a polishing pad. The conditioning member
A process using a retaining ring assembly of a carrier head to precompress a polishing pad to reduce or minimize the edge effect in a chemical mechanical polishing process.
A carrier uses multiple bellows to form two pressure chambers between the housing and carrier base and retaining ring assembly. By pressurizing the first chamber, an even load can be applied across the substrate. By pressurizing the second chamber, the retaining ring can pressed against
