Claim Text:
1. A substrate processing method of performing a predetermined process onto a substrate, on which a pattern mask is formed by exposure and development treatments, comprising: mounting the substrate on a mounting table installed in a process space formed in a processing vessel; heating the substrate mounted on the mounting table by a heating part to a temperature higher than a dew-point temperature of a solvent; evaporating the solvent from an evaporation source formation part installed in the process space opposite to the entire surface of the substrate to form an internal atmosphere of the process space to a saturated vapor atmosphere of the solvent; forming a compartmented state by a compartment mechanism; the compartmented state representing a state that a first section, in which the evaporation source formation part is installed in the process space, and a second section for transferring the substrate between the outside of the processing vessel and the mounting table, are partitioned such that atmospheres of the first and second sections are blocked from each other; forming an open state by compartment mechanism, the open state representing a state that the atmospheres of the first and second sections are opened to each other; opening and closing a substrate transfer hole formed in the processing vessel with respect to the second section being in the partition state; and exhausting the second section when in the compartmented state and removing a solvent atmosphere of the second section.
