Abstract

A substrate processing apparatus comprises an indexer block, an anti-reflection film processing block, a resist film processing block, a development processing block, a drying processing block, and an interface block. An exposure device is arranged adjacent to the interface block. The drying processing block comprises a drying processing group. The interface block comprises an interface transport mechanism. A substrate is subjected to exposure processing by the exposure device, and subsequently transported to the drying processing group by the interface transport mechanism. The substrate is subjected to cleaning and drying processing by the drying processing group.
