摘要： A polishing apparatus (30) has a polishing surface (32), a top ring (36) for holding a wafer (W), motors (46, 56) to move the polishing surface (32) and the wafer (W) relative to each other at a relative speed, and a vertical movement mechanism (54) to press the wafer (W) against the polishing surface (32) under a pressing pressure. The polishing apparatus (30) also has a controller (44) to adjust a polishing condition in a non-Preston range in which a polishing rate is not proportional to a product of the pressing pressure and the relative speed. The polishing apparatus (30) can simultaneously achieve uniform supply of a chemical liquid to a surface of the wafer (W) and a uniform polishing rate within the surface of the wafer (W).

摘要： In the CMP of films of semiconductor devices, pulsed measuring radiation is directed onto a surface to be polished of a rotating wafer. At this point, the pulse repetition rate of the pulsed measuring radiation is determined so that the pulse measuring radiation is directed only onto a specified portion of the surface of each semiconductor device. Thereby, reflection data can be obtained only from the specified portion of a film to be polished, allowing accurate measurements of the thickness of the specified portion of the film in the middle of polishing.
