摘要： A polishing apparatus applicable to a dry-in/dry-out polishing system is capable of increasing the capacity of processing substrates to be polished, e.g. semiconductor wafers, per unit of time and per unit area of installation. A polishing unit includes a turntable having a polishing surface, and at least two wafer carriers each adapted to hold a wafer and to press the wafer against the polishing surface. Each wafer carrier is supported by a pivot shaft and movable between a polishing position where the wafer is polished on the turntable and a transfer position for transferring the wafer. The at least two wafer carriers can be situated at the polishing position simultaneously and also alternately.

摘要： A polishing apparatus is used for polishing a workpiece such as a semiconductor wafer to a flat mirror finish. The polishing apparatus, includes a turntable having a polishing surface thereon, and a top ring for holding a workpiece to be polished and pressing the workpiece against the polishing surface on the turntable. A pusher is disposed in a position for transferring the workpiece to and from the top ring, and has a workpiece support which can be lifted to a position close to the top ring for transferring the workpiece to and from the top ring. When the workpiece support receives a polished workpiece and is lowered, a cleaning liquid is ejected substantially simultaneously from three cleaning nozzle units that are disposed in respective three positions to clean the upper and lower surfaces of the workpiece and the lower surface of the top ring.

摘要： This invention relates to a polishing machine for polishing an article such as a semiconductor wafer. A movable arm is located at a liquid supply position for supplying a liquid such as a polishing liquid onto a polishing surface of a turntable. The arm is also adapted to be moved to and held at a retracted position radially outside the polishing surface. At the liquid supply position, liquid supply nozzles supported on the arm are brought into a condition such that the nozzles are close to a position on the polishing surface where the liquid is to be supplied, whereby the liquid is accurately supplied onto the position. Holding the arm at the retracted position makes it easy to conduct a maintenance work for the polishing surface and so on.

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.
