  • Patent number: 11851745
    Abstract: A pre-drying processing liquid containing a sublimable substance that changes to gas without passing through to a liquid and a solvent in which the sublimable substance dissolves is supplied to a front surface of a substrate on which a pattern has been formed. Thereafter, the solvent is evaporated from the pre-drying processing liquid on the front surface of the substrate to thereby form a solidified body containing the sublimable substance on the front surface of the substrate. Thereafter, the solidified body is sublimated and thereby removed from the front surface of the substrate. A value acquired by multiplying a ratio of the thickness of the solidified body to the height of the pattern by 100 is greater than 76 and less than 219.
