Abstract
A substrate drying method for drying a front surface of a substrate having a pattern includes a sublimation-agent-liquid-film placing step of placing a liquid film of a liquid sublimation-agent on the front surface of the substrate, a high vapor-pressure liquid placing step of placing a liquid film of a high vapor-pressure liquid that has vapor pressure higher than the sublimation agent and that does not include water on the liquid film of the sublimation-agent placed on the front surface of the substrate, a vaporizing/cooling step of losing vaporization heat in response to vaporization of the high vapor-pressure liquid, and, cooling the sublimation-agent, and, as a result, solidifying the liquid film of the sublimation-agent, and, forming a sublimation-agent film on the front surface of the substrate, and a sublimating step of sublimating the sublimation-agent film.
