摘要:
A polishing method includes rotating a substrate, performing a first polishing process of pressing a polishing tape against an edge portion of the substrate by a pressing member, with a portion of the polishing tape projecting from the pressing member inwardly in a radial direction of the substrate, to polish the edge portion of the substrate and bend the portion of the polishing tape along the pressing member, and performing a second polishing process of pressing the bent portion of the polishing tape inwardly in the radial direction of the substrate by the pressing member to further polish the edge portion of the substrate.
