  • Publication number: 20140020721
    Abstract: A substrate processing method and apparatus for preventing evaporation of an anti-drying fluorine-containing organic solvent from a substrate during transportation of the substrate into a processing container and can prevent decomposition of a fluorine-containing organic solvent in the processing container. A substrate, the surface of which is covered with a first fluorine-containing organic solvent, is carried into a processing container. The first fluorine-containing organic solvent is removed from the substrate surface by forming a high-pressure fluid atmosphere of a mixture of the first fluorine-containing organic solvent and a second fluorine-containing organic solvent, having a lower boiling point than the first fluorine-containing organic solvent, in the processing container e.g. by supplying a high-pressure fluid of the second fluorine-containing organic solvent into the processing container.
