| 摘要 |
There is provided a substrate processing apparatus and method which employs the so-called batch processing method of processing a plurality of substrates simultaneously, thereby increasing the throughput, and which can carry out processing, such as electroless plating, stably and securely with a relatively simple apparatus. The substrate processing apparatus includes: a processing bath (14) for holding a processing liquid (12); and a substrate holder (16) which is vertically movable relative to the processing bath (14) and which includes a plurality of substrate holding portions (40) for holding a plurality of substrates (W) in parallel; wherein each substrate holding portion (40) has a substrate stage (48) and substrate presser (54), which can move close to or away from each other and can grip therebetween a peripheral portion of a substrate to thereby hold the substrate with its back surface sealed, and has a heating medium flow passage (62) for passing a heating medium therethrough so as to regulate the temperature of the substrate holding portion (40).
