Abstract
A substrate dual-side processing apparatus has a processor to apply a specific process to a front surface and a rear surface of a substrate, a reversing unit to reverse the substrate and a substrate-transfer mechanism to transfer the substrate between the processor and the reversing unit. The reversing unit has a holder for holding the substrate when the substrate is being transferred to and from the substrate-transfer mechanism and a rotating mechanism for rotating the substrate, thus the substrate being reversed while held by the holders. The reversing unit may have a pair of holders for holding the substrate at the front and rear surfaces, a drive mechanism for driving the pair of holders so that the holders become close to or apart from each other and a rotating mechanism for rotating the substrate, thus the substrate being reversed while held by the holders.
