Abstract:
A method of polishing a substrate on which a first layer and a second layer are formed, comprising:bringing the substrate to be polished into contact with a polishing surface of a polishing table; polishing the first layer of the substrate while supplying a first polishing liquid between the first layer of the substrate and the polishing surface of the polishing table; cleaning the polishing surface to remove residue of the first polishing liquid from the polishing surface after said polishing the first layer; and polishing the second layer of the substrate while supplying a second polishing liquid between the second layer of the substrate and the polishing surface of the polishing table after said cleaning the polishing surface; wherein said polishing the first layer and said polishing the second layer each comprises rotating the substrate about a center axis of the substrate and controlling an attitude of the substrate with a controller; and wherein said polishing the first layer and said polishing the second layer each comprises the substrate extending outwardly of an outer periphery of the polishing surface of the polishing table during said polishing the first layer and said polishing the second layer.
