Claim 0:
1. A substrate processing apparatus comprising:
a substrate holder configured to hold a substrate;
a first cleaning body configured to clean one surface of an upper surface and a lower surface of the substrate held by the substrate holder by ejecting fluid thereto or by coming into contact therewith;
a first mover including a first arm configured to horizontally move the first cleaning body;
a second cleaning body configured to clean a remaining surface of the upper surface and the lower surface of the substrate held by the substrate holder by coming into contact therewith;
a second mover including a second arm configured to horizontally move the second cleaning body;
a third cleaning body configured to clean a side end of the substrate held by the substrate holder by coming into contact therewith;
a housing configured to surround the first mover and the second mover; and, a controller configured to control an overall operation of the substrate processing apparatus,
wherein the controller is programmed to:
perform a both-surface cleaning processing in which the first cleaning body, which ejects the fluid to the one surface or is brought into contact with the one surface, from a position at a center of the substrate to a position overlapping the second cleaning body which is stopped at a position deviated from the center of the substrate, and subsequently moves both the first cleaning body and the second cleaning body, which is in contact with the remaining surface of the upper surface and the lower surface of the substrate and rotated around a first vertical axis, horizontally in synchronization with each other toward an outer peripheral portion of the substrate, and
perform a side end cleaning processing in which the third cleaning body is rotated around a second vertical axis and brought into contact with the side end of the substrate to clean the side end of the substrate while simultaneously performing the both-surface cleaning processing.
