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 method for manufacturing a semiconductor device makes it possible to efficiently polish with a polishing tape a peripheral portion of a silicon substrate under polishing conditions particularly suited for a deposited film and for silicon underlying the deposited film. The method includes pressing a first polishing tape against a peripheral portion of a device substrate having a deposited film on a silicon surface while rotating the device substrate at a first rotational speed, thereby removing the deposited film lying in the peripheral portion of the device substrate and exposing the underlying silicon. A second polishing tape is pressed against the exposed silicon lying in the peripheral portion of the device substrate while rotating the device substrate at a second rotational speed, thereby polishing the silicon to a predetermined depth.

摘要： A polishing method can obtain a good polishing profile which, for example, will not cause peeling of a semiconductor layer from a silicon substrate. The polishing method includes: positioning a polishing head at a position above a polishing start position in an edge portion of a rotating substrate; lowering a polishing tool of the polishing head until the polishing tool comes into contact with the polishing start position in the edge portion of the rotating substrate and a pressure between the polishing tool and the polishing start position reaches a set pressure; allowing the polishing tool to stay at the polishing start position for a predetermined amount of time; and then moving the polishing head toward a peripheral end of the substrate while keeping the polishing tool in contact with the edge portion of the rotating substrate at the set pressure.

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.
