  • Patent number: 10199240
    Abstract: A substrate processing method and apparatus which can remove an anti-drying liquid, which has entered a three-dimensional pattern with recessed portions formed in a substrate, in a relatively short time. The substrate processing method includes the steps of: carrying a substrate, having a three-dimensional pattern formed in a surface, into a processing container, said pattern being covered with an anti-drying liquid that has entered the recessed portions of the pattern; heating the substrate and supplying a pressurizing gas or a fluid in a high-pressure state into the processing container, thereby forming a high-pressure atmosphere in the processing container before the anti-drying liquid vaporizes to such an extent as to cause pattern collapse and bringing the anti-drying liquid into a high-pressure state while keeping the liquid in the recessed portions of the pattern; and thereafter discharging a fluid in a high-pressure state or a gaseous state from the processing container.

  • Patent number: 10096462
    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.
