    摘要: A polishing method of polishing a substrate while preventing coarse particles from being discharged onto a polishing pad is disclosed. In this polishing method, a substrate is brought into sliding contact with a polishing pad while a polishing liquid, which has passed through a filter, is supplied onto the polishing pad. The polishing method includes: passing the polishing liquid through the filter while increasing a physical quantity of the polishing liquid until the physical quantity reaches a predetermined set value, the physical quantity being one of flow rate and pressure of the polishing liquid; and polishing the substrate W on the polishing pad while supplying the polishing liquid that has passed through the filter onto the polishing pad.

    摘要: The invention simulates polishing amount taking into account pressure concentration that occurs in the vicinity of the edge of a substrate when a small-diameter buffing pad overhangs the substrate to be buffed.One embodiment of the invention provides a method for simulating polishing amount in a case where a polishing pad of a smaller size than a substrate is used to buff the substrate. The method includes measuring distributions of pressure that is applied from the polishing pad to the substrate according to each overhang amount of the polishing pad relative to the substrate by using a pressure sensor, and correcting the pressure that is used in the polishing amount simulation in accordance with the overhang amounts and the measured pressure distributions.

    摘要: A technique is disclosed that can allow an elastic membrane to be inflated into a desired shape when a workpiece is released from a polishing head, or when the workpiece is held on the polishing head, thereby avoiding excessive stress on the workpiece. The method includes supplying a gas into a first pressure chamber and a second pressure chamber at a first flow rate and a second flow rate regulated by a first flow-rate control valve and a second flow-rate control valve to inflate an elastic membrane of a polishing head when a polished workpiece is released from the polishing head, or when a workpiece to be polished is held on the polishing head. The first pressure chamber and the second pressure chamber are formed by the elastic membrane.
