Patent ID: 7905195

Claim:
A floating-type substrate conveying and processing apparatus comprising: a floating stage formed of a porous member and including a plurality of suction apertures airtightly defined in a porous portion of the porous member, the floating stage injecting gas through the porous portion and sucking gas through the suction apertures to float a substrate to be processed placed on the porous portion, the suction apertures being arranged in rows, the rows being inclined with respect to a substrate conveying direction, which substrate conveying direction is parallel to the floating stage, and the rows being inclined with respect to a direction that is both parallel to the floating stage and transverse to the substrate conveying direction; a process liquid supplier placed above the floating stage via the substrate to supply a process liquid to a surface of the substrate; and a moving mechanism to hold the substrate as detachable at opposite ends of the substrate, at a floating height of the substrate, and to move the substrate on the floating stage in the substrate conveying direction.
