System for real-time control of semiconductor wafer polishing |
摘要 |
A system for polishing a semiconductor wafer, the system comprising a wafer polishing assembly for polishing a face of a semiconductor wafer at a polishing rate and a polishing uniformity, the wafer polishing assembly including a platen subassembly defining a polishing area, and 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 a controller selectively adjusting one of a plurality of adjustable polishing parameters during polishing of the wafer.
