Abstract:
The present invention relates to a method and an apparatus for polishing a surface of a substrate having a film whose thickness varies along a circumferential direction of the substrate. The polishing method includes: obtaining a film-thickness distribution in a circumferential direction of a substrate (W); determining a first area having a maximum or minimum film thickness based on the film-thickness distribution; rotating a polishing table ( 3 ) holding a polishing pad ( 2 ); pressing a surface of the substrate (W) against the polishing pad ( 2 ) while rotating the substrate by a polishing head ( 1 ); and polishing the first area at a removal rate different from that of a second area in the surface of the substrate (W).

Claim (Index 7):
The polishing method according to  claim 1 , wherein pressing the surface of the substrate against the polishing pad comprises pressing the surface of the substrate against the polishing pad with an elastic membrane of the polishing head, while rotating the substrate by the polishing head, the polishing head having a membrane holder holding the elastic membrane, the membrane holder being inclined upward or downward in a direction from the first area toward the second area.
