Claim 5:
6. A substrate processing method by using a substrate processing apparatus provided with a holding unit and a processing unit, comprising:
treating at least a major surface side of a substrate with a first liquid, a structural body being provided on the major surface of the substrate, the structural body having a top surface, a side surface and a bottom surface, the bottom surface contacting the major surface of the substrate;
bringing a second liquid into contact with the structural body and the substrate, the second liquid being not a rinsing liquid;
forming a solid member by changing at least a portion of the second liquid into a solid, the solid member being formed to be in contact with at least the side surface of the structural body and to prevent the structural body from collapse when drying after the liquid treatment by the second liquid, the changing at least the portion of the second liquid into the solid including at least one of a pressure application process, a spin drying process, a gas supply drying process, or a natural drying process;
providing the substrate provided with the solid member on the holding unit;
blowing a gas onto the major surface of the substrate for heating the substrate by using a nozzle provided with the processing unit; and
removing the solid member from a solid phase directly to a gaseous phase, the solid member being removed using sublimation by heating,
wherein the forming the solid member includes making a lower portion of the structural body and making an upper portion of the structural body on the lower portion and a part of the upper portion is apart from the lower portion.
