Abstract:
A chemical mechanical polishing apparatus includes a liquid filled bladder that exerts force on the back of the substrate being polished. The bladder can be a multi-chamber bladder having chambers filled with different ratios of hot and cold water. Eddy current detection during the polishing can be used to control the polishing process parameters.

Claim (Index 1):
A method of polishing a substrate, comprising:\n chemically mechanically polishing a substrate in a polishing apparatus having a bladder; measuring an eddy current in the substrate; determining a temperature of the substrate at a plurality of locations on the substrate; and providing a temperature control liquid to the bladder to at least one of cool or heat and maintain the substrate at substantially the same temperature while polishing the substrate, wherein at least one of a temperature or pressure of the cooling liquid is based at least in part on the measured eddy current.
