Abstract:
1. A method for drying under reduced pressure with which a solvent in a coating liquid is dried by placing a substrate having the coating liquid applied in a pressure-reduced atmosphere, comprising the steps of: mounting the substrate on a substrate mount portion provided in an airtight container; positioning a straightening vane so as to face a surface of the substrate mounted on the substrate mount portion with a gap interposed; evacuating and reducing pressure in the airtight container down to a pressure at which a solvent component actively evaporates from said coating liquid; and varying a flow rate set value at least in two steps while the solvent component is actively evaporating from said coating liquid; wherein the varying the flow rate set value at least in two steps includes varying the flow rate set value from a first flow rate set value to a second flow rate set value larger than the first flow rate set value.
