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 13):
The vapor supplying method according to  claim 12 , further comprising the steps of:\n c) introducing said mixed liquid stored in said mixed liquid storage into a circulation dewatering unit communicatively connected to said mixed liquid storage, dewatering said mixed liquid in said circulation dewatering unit, and returning said mixed liquid after being dewatered from said circulation dewatering unit to said mixed liquid storage; and d) after a water concentration in said mixed liquid stored in said mixed liquid storage becomes a first designated value or less and larger than a second designated value as a result of said step c), generating said mixed vapor from said mixed liquid stored in said mixed liquid storage and emitting said mixed vapor to an exhaust mechanism outside said mixed liquid storage, wherein in said step a), said mixed liquid containing water having a ratio of 0.1% by weight or less and having a concentration larger than said first designated value is supplied to said mixed liquid storage, in said step b), after a water concentration in said mixed liquid becomes said second designated value or less as a result of said step d), said mixed vapor is generated from said mixed liquid stored in said mixed liquid and said mixed vapor is supplied to said vapor supply pipe, said first designated value is a value not exceeding a water concentration while the concentration of said low surface tension liquid is an azeotropic concentration, said azeotropic concentration being a concentration at which the concentration of said low surface tension liquid contained in said mixed liquid and the concentration of vapor of said low surface tension liquid contained in said mixed vapor generated from said mixed liquid are the same, and said second designated value is smaller than said first designated value.
