Abstract:
The present invention relates to a polishing apparatus and a polishing method for polishing a substrate, such as a wafer, and more particularly to a polishing apparatus and a polishing method for polishing an edge portion of a wafer with use of a polishing tape. The polishing apparatus includes a substrate holder ( 1 ) configured to hold and rotate a substrate (W), and a polishing unit ( 7 ) configured to polish an edge portion of the substrate (W) with use of a polishing tape ( 5 ). The polishing unit ( 7 ) includes: a disk head ( 12 ) having a circumferential surface for supporting the polishing tape ( 5 ); and a head moving device ( 50 ) configured to move the disk head ( 12 ) in a tangential direction of the substrate (W) and to bring the polishing tape ( 5 ) on the circumferential surface of the disk head ( 12 ) into contact with the edge portion of the substrate (W).

Claim (Index 10):
The polishing apparatus according to  claim 9 , wherein the polishing unit further includes:\n a base supporting the disk head; a horizontal linear guide extending parallel to the tangential direction of the substrate, the base being movably supported by the linear guide, the disk head being movable together with the base.
