  • Publication number: 20070298694
    Abstract: A wafer polishing head according to the invention is disclosed. In the wafer polishing head, an automatic control device is additionally installed outside the wafer polishing head for automatically adjusting a pressure applied on a retaining ring. This ensures the bottom of the retaining ring always lower than that of a carrier, thereby preventing a semiconductor wafer from slip during polishing. Furthermore, a liquid pressure generated to press the carrier can efficiently alleviate wabble during polishing. Therefore, the wafer polishing head of the invention can greatly improve a polishing uniformity.
