Abstract:
1. A substrate processing method, comprising: treating a substrate with a first liquid, the substrate having a structural body formed on at least a major surface of the substrate; forming a support member supporting the structural body by bringing a second liquid into contact with the substrate wetted by the first liquid, and changing at least a portion of the second liquid into a solid; and removing the support member by a sublimation of the support member from a solid phase directly to a gaseous phase by a simultaneous pressure reduction and heating process on the support member, wherein the heating process uses only a hot plate, wherein the support member includes a substance including at least one selected from the group consisting of a methacrylic resin material; a styrene resin material; a perfluoro group, iodine, naphthalene, and benzotriazole.
