Claim 0:
1. A substrate processing apparatus comprising:
a table for supporting a substrate;
a pad holder for holding a polishing pad for polishing the substrate supported by the table;
an elevating mechanism for elevating the pad holder with respect to the substrate;
a swing mechanism for swinging the pad holder in a radial direction of the substrate;
a supporting member for supporting the polishing pad swung to outside the table by the swing mechanism; and
a driving mechanism for adjusting at least one of a height and a distance to the substrate of the supporting member while polishing the substrate,
wherein the supporting member has a support surface for supporting a polishing surface of the polishing pad, the polishing surface being to be brought into contact with the substrate, the support surface of the supporting member having an implanted vacuum passage communicated with a vacuum member.
