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 4):
The polishing method according to  claim 1 , wherein polishing the first area at a removal rate different from that of the second area in the surface of the substrate comprises polishing the first area at a removal rate different from that of the second area by increasing or decreasing a load applied from the polishing head to an entirety of the surface of the substrate when the first area is located outwardly of the second area in a radial direction of the polishing table.
