    摘要： A polishing apparatus can effectively prevent abrasive particles from falling off a polishing tape during polishing. The polishing apparatus includes: a polishing head for polishing a peripheral portion of a substrate by pressing a surface of a polishing tape, having abrasive particles fixed on the surface, against the peripheral portion of the substrate while allowing the polishing tape to travel in one direction; and a conditioning apparatus, disposed upstream of the polishing head in the traveling direction of the polishing tape, for conditioning the surface of the polishing tape in advance in order to prevent the abrasive particles from falling off the surface of the polishing tape during polishing.

    摘要： A substrate holding mechanism, a substrate polishing apparatus and a substrate polishing method have functions capable of minimizing an amount of heat generated during polishing of a substrate to be polished and of effectively cooling a substrate holding part of the substrate holding mechanism, and also capable of effectively preventing a polishing solution and polishing dust from adhering to an outer peripheral portion of the substrate holding part and drying thereon. The substrate holding mechanism has a mounting flange, a support member 6 and a retainer ring. A substrate to be polished is held on a lower side of the support member surrounded by the retainer ring, and the substrate is pressed against a polishing surface of a polishing table. The mounting flange is provided with a flow passage contiguous with at least the retainer ring. A temperature-controlled gas is supplied through the flow passage to cool the mounting flange, the support member and the retainer ring. The retainer ring is provided with a plurality of through-holes communicating with the flow passage to spray the gas flowing through the flow passage onto the polishing surface of the polishing table.

    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 having a polishing surface, a polishing head having at least one elastic membrane configured to form a plurality of pressure chambers for being supplied with a pressurized fluid, and a controller configured to control supply of the pressurized fluid to the pressure chambers. The controller controls supply of the pressurized fluid so that the pressurized fluid is supplied first to the pressure chamber located at a central portion of the substrate when the substrate is brought into contact with the polishing surface, and then the pressurized fluid is supplied to the pressure chamber located at a radially outer side of the pressure chamber located at the central portion of the substrate.
