摘要： A substrate holding apparatus prevents a substrate from slipping out and allows the substrate to be polished stably. The substrate holding apparatus has a top ring body for holding and pressing a substrate against a polishing surface, and a retainer ring for pressing the polishing surface, the retainer ring being disposed on an outer circumferential portion of the top ring body. The retainer ring includes a first member made of a magnetic material and a second member having a magnet disposed on a surface thereof which is held in abutment against the first member.

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.
