Abstract
A substrate processing method includes removing a dissolved gas in a processing liquid; forming a liquid film of the processing liquid covering a surface of a substrate, by supplying, onto the surface of the substrate, the processing liquid from which the dissolved gas is removed; carrying the substrate having the liquid film formed thereon into a processing vessel; and drying the surface of the substrate by flowing a processing fluid into the processing vessel while maintaining an internal pressure of the processing vessel, in which the substrate having the liquid film formed thereon is accommodated, at a pressure allowing the processing fluid to be maintained in a supercritical state, to replace the processing liquid covering the surface of the substrate with the processing fluid, and, then, by vaporizing the processing fluid.
