Abstract
An apparatus for polishing a substrate includes a rotatable polishing table supporting a polishing pad, a substrate holder configured to hold the substrate and press the substrate against a polishing surface of the polishing pad on the rotating polishing table so as to polish the substrate, and a pad-temperature detector configured to measure a temperature of the polishing surface of the polishing pad. The apparatus also includes a pad-temperature regulator configured to contact the polishing surface to regulate the temperature of the polishing surface, and a temperature controller configured to control the temperature of the polishing surface by controlling the pad-temperature regulator based on information on the temperature of the polishing surface detected by the pad-temperature detector.
