Abstract

A process block including a group of liquid-process related unit blocks, a first heating-process related block arranged on a carrier block side of the group of unit blocks, and a second heating-process related block arranged on an interface block side of the group of unit blocks. The group of liquid-process unit blocks includes doubled unit blocks for preprocessing for forming an antireflection film and a resist film, doubled unit blocks for post-processing for forming an upper layer film and performing a cleaning operation before exposure, and a unit block for developing. The first heating-process related block heats a substrate coated with a resist liquid and a substrate that has been developed. The second heating-process related block heats a substrate that has been exposed but is not yet developed, a substrate on which an antireflection film has been formed and a substrate on which an upper layer film has been formed.
