Abstract:
A polishing apparatus for polishing a substrate is provided. The polishing apparatus includes: a polishing table holding a polishing pad; a top ring configured to press the substrate against the polishing pad; first and second optical heads each configured to apply the light to the substrate and to receive reflected light from the substrate; spectroscopes each configured to measure at each wavelength an intensity of the reflected light received; and a processor configured to produce a spectrum indicating a relationship between intensity and wavelength of the reflected light. The first optical head is arranged so as to face a center of the substrate, and the second optical head is arranged so as to face a peripheral portion of the substrate.

Claim (Index 12):
The polishing apparatus according to  claim 1 , wherein the top ring has a mechanism capable of independently pressing the central portion and the peripheral portion of the substrate, and\n wherein the polishing apparatus further comprises a controller that determines polishing loads to the central portion and the peripheral portion of the substrate based on the thickness of the central portion and the peripheral portion of the substrate.
