Beschreibung
Zusammenfassung:	A substrate treatment method is provided, which includes: an organic solvent replacing step of supplying an organic solvent, whereby a liquid film of the organic solvent is formed on the substrate as covering the upper surface of the substrate to replace a rinse liquid with the organic solvent; a substrate temperature increasing step of allowing the temperature of the upper surface of the substrate to reach a first temperature level higher than the boiling point of the organic solvent after the formation of the organic solvent liquid film, whereby a vapor film of the organic solvent is formed below the entire organic solvent liquid film between the organic solvent liquid film and the substrate to levitate the organic solvent liquid film above the organic solvent vapor film; and an organic solvent removing step of removing the levitated organic solvent liquid film from above the upper surface of the substrate.
