System for real-time control of semiconductor wafer polishing including heater

摘要

A system for polishing a semiconductor wafer, the system comprising a platen subassembly defining a polishing area; a polishing head selectively supporting a semiconductor wafer and holding a face of the semiconductor wafer in contact with the platen subassembly to polish the wafer face; and means for heating the wafer while the wafer face is being polished.
