Patent ID: 8286293

Claim:
A substrate processing apparatus disposed adjacent to an exposure device that subjects a substrate to exposure processing by means of a liquid immersion method, the substrate processing apparatus comprising: a processing section for subjecting a substrate to processing, the substrate having one surface and another surface opposing the one surface; and an interface provided adjacent to one end of the processing section for receiving and transferring the substrate between the processing section and the exposure device, wherein: the processing section includes a photosensitive film forming unit that forms a photosensitive film made of a photosensitive material on one surface of the substrate before the exposure processing by the exposure device, and at least one of the processing section or the interface comprises a substrate cleaning device that cleans the substrate after the formation of the photosensitive film by the photosensitive film forming unit and before the exposure processing, by the exposure device, the substrate cleaning device comprising: a substrate rotation holding device that rotates the substrate while holding the substrate; a cleaning brush configured to come into contact with the substrate held in the substrate rotation holding device; a driving mechanism that moves the cleaning brush; and a brush rotating mechanism that rotates the cleaning brush around a rotating shaft in a direction substantially perpendicular to the one surface of the substrate held in the substrate rotation holding device; the cleaning brush comprising: a first cleaning surface configured to come into contact with a bevel region on a side of another surface of the substrate held by the substrate rotation holding device; and an annular plane-shaped second cleaning surface configured to come into contact with a peripheral portion of the another surface of the substrate held by the substrate rotation holding device, wherein the first and second cleaning surfaces are integrally provided with the rotating shaft as its center such that: the driving mechanism moves the cleaning brush to a position where the cleaning brush does not come into contact with the one surface of the substrate, the bevel region on the side of the one surface of the substrate, and an end surface region of the substrate, but the first and second cleaning surfaces of the cleaning brush come into contact with the bevel region on the side of the another surface of the substrate and the peripheral region of the another surface of the substrate simultaneously.
