Abstract:
When a substrate on which a fine pattern is formed is dried with vapor, prevention of collapse of the pattern due to water originally contained in IPA to be stored has been a problem to be solved. A mixed liquid stored in a mixed liquid storage is vaporized to generate mixed vapor containing the IPA and water (water vapor). Then, a vapor dewatering unit connected to a vapor supply pipe through which the mixed vapor is fed removes water in the mixed vapor. This can reduce the concentration of water originally contained in the IPA to be stored before the IPA is supplied to the substrate, thereby suppressing collapse of the pattern.

Claim (Index 1):
A vapor supplying apparatus used for vapor drying process of supplying vapor of a low surface tension liquid to a main surface of a substrate to which a processing liquid adheres, said low surface tension liquid having surface tension same as or lower than that of said processing liquid, said vapor supplying apparatus comprising:\n a mixed liquid storage that stores a mixed liquid containing said low surface tension liquid and water; a vapor generator that generates mixed vapor as vapor of said mixed liquid from said mixed liquid stored in said mixed liquid storage; a vapor supply pipe connected to said mixed liquid storage and through which said mixed vapor generated by said vapor generator is supplied to said substrate; and a vapor dewatering unit interposed in said vapor supply pipe, said vapor dewatering unit removing water from said mixed vapor passing through said vapor supply pipe, wherein said vapor dewatering unit includes at least one of a separating section and an absorbing section, said separating section separates water from said mixed vapor, and said absorbing section absorbs water in said mixed vapor.
