PROBLEM TO BE SOLVED: To provide a substrate processing method and a substrate processing apparatus which suppress pattern collapse when a substrate is dehydrated after a liquid treatment.SOLUTION: There is provided a substrate processing method. The substrate processing method includes a process of treating a substrate that has a structure formed on at least a principal plane by liquid. The substrate processing method further includes a process of bring a solution into contact with the structure wetted with the liquid and forming a supporting material that supports the structure by changing at least a part of the solution into a solid state by at least any one of the steps of: reacting the solution; decreasing the amount of solvent contained in the solution; and depositing at least a part of materials solved in the solution. The substrate processing method further includes a process of removing the supporting material by changing the supporting material from a solid phase to a vapor phase without passing through a liquid phase.

PROBLEM TO BE SOLVED: To provide a method for forming a resist pattern achieving miniaturization of pattern dimensions and improving pattern uniformity.SOLUTION: The method for forming a resist pattern includes steps of: forming a resist film on a support body by using a resist composition that contains a basic component (A) the solubility of which with an organic solvent is decreased by an action of an acid, and an acid generator component (B) generating an acid by exposure; exposing the resist film; forming a resist pattern by patterning the resist film by negative development using a developing solution containing the organic solvent; forming a coating film by applying a coating film forming agent on the resist pattern; heat treating the coating film at a temperature lower than the softening point of the resist pattern to thermally shrink the coating film, thereby, reducing an interval between the resist patterns; and removing the coating film.
