Abstract:
A polishing head for a chemical mechanical polishing apparatus is provided which includes at least two polishing head zones configured to provide different temperatures for transferring heat to at least two zones of a substrate corresponding to the at least two polishing head zones. The present disclosure addresses chemical mechanical polishing which allows a control of the polishing profile even if slurries are used, which show almost no dependency between polishing rate and down force.
