    摘要: The present invention provides a dressing method of dressing a polishing pad used in a polishing apparatus for polishing a substrate. This method includes repetitively moving the dresser on an upper surface of the polishing pad in a radial direction of the polishing pad so as to perform a dressing process on the polishing pad, during the dressing process, measuring a height of an upper surface of the polishing pad at a predetermined point in one of plural zones on the polishing surface, and repeating the repetitive moving of the dresser and the measuring of the height of the upper surface of the polishing pad so as to measure the height of the upper surface of the polishing pad in all of the plural zones.

    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 substrate holding apparatus configured to hold the substrate and to press the substrate against the polishing surface, and a controller. The substrate holding apparatus includes an elastic membrane configured to form a substrate holding surface which is brought into contact with the substrate, a carrier provided above the elastic membrane, at least one pressure chamber formed between the elastic membrane and the carrier, and an infrared light detector configured to measure thermal energy from the elastic membrane. The controller calculates an estimate value of a temperature of the elastic membrane using a measured value of the infrared light detector.
