  • Publication number: 20210324509
    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.

Two plates (3, 4) are provided between each of the batteries (2), and each of the batteries (2) is compressed by shifting the two plates (3, 4) in directions away from each other. A pair of frame members (10, 20) having opposing surfaces (11, 21) extending along the stacking direction of the batteries (2) are disposed face to face so as to sandwich the batteries (2) in a direction perpendicular to the stacking direction of the batteries. Wedge-shaped spacers (12, 22) inserted between the two plates (3, 4) are provided respectively on the opposing surfaces. By narrowing the gap between the pair of frame members (10, 20), the spacers (12, 22) are allowed to advance inwardly between the two plates (3, 4) so that the two plates are shifted in directions away from each other, whereby the batteries are compressed.
