摘要 A polishing apparatus is used for polishing a substrate such as a semiconductor wafer to a flat mirror finish. The polishing apparatus includes a polishing table (100) having a polishing surface (101a), a top ring body (2) configured to hold and press a substrate against the polishing surface (101a), and a retainer ring (3) provided at an outer peripheral portion of the top ring body (2) and configured to press the polishing surface (101a). A fulcrum for receiving a lateral force applied from the substrate to the retainer ring (3) during polishing of the substrate is located above a central portion of the substrate.
