Claim 9:
10. 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 swing mechanism includes a first arm for holding the pad holder, a second arm for holding a cleaning tool holder for holding a cleaning tool, a third arm for holding a pad holder for holding a polishing pad with a diameter different from a diameter of the polishing pad, a fourth arm for holding a photographing member, a swing shaft that supports the first, second, third, and fourth arms, and a rotation drive mechanism for rotatably driving the swing shaft, and
each of the first, second, third, and fourth arms is radially arranged in a peripheral area of the swing shaft.
