Abstract:
A gas treatment apparatus, comprising:a sealing vessel for holding a coated substrate; a heating means for heating the inside of said sealing vessel so as to gelatinize the coating of the substrate; a gas supplying path for supplying vapor of a solvent to said sealing vessel; an exhausting path for exhausting gas out of said sealing vessel; a gas dispersing chamber disposed in the middle of said gas supplying path in a wall of said sealing vessel, having a plurality of gas supplying openings, connected to said sealing vessel, for dispersing gas in said gas supplying path to said sealing vessel, the inner temperature of said gas dispersing chamber being kept at almost the same as the inner temperature of said sealing vessel; and a solvent vapor generating portion, heated at a slightly higher temperature than the inner temperature of said gas dispersing chamber, for generating vapor of the solvent that becomes saturated vapor at the inner temperature of said sealing vessel.
