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 9):
The vapor supplying apparatus according to  claim 6 , further comprising:\n a sensor that senses the concentration of said low surface tension liquid or that of water contained in said mixed liquid stored in said mixed liquid storage; and a controller that controls said vapor generator and said exhaust unit based on said concentration sensed by said sensor, wherein if a water concentration in said mixed liquid stored in said mixed liquid storage is a first designated value or less and larger than a second designated value, said controller makes said vapor generator generate said mixed vapor from said mixed liquid stored in said mixed liquid storage and makes said exhaust unit emit said mixed vapor to said exhaust mechanism, if a water concentration in said mixed liquid stored in said mixed liquid storage is said second designated value or less, said controller makes said vapor generator generate said mixed vapor from said mixed liquid stored in said mixed liquid storage and supplies said mixed vapor 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.
