Claim:
1. A method of manufacturing a semiconductor device comprising: attaching, by a liquid treatment, a first liquid to a surface of a semiconductor substrate having a fine pattern formed therein; substituting the first liquid attached to the surface of the semiconductor substrate with a solution, the solution comprising a sublimate dissolved in a second liquid; vaporizing the second liquid and precipitating the sublimate to the surface of the semiconductor substrate to form a solid precipitate comprising the sublimate; and removing the precipitate by sublimation, the sublimate comprising at least one material selected from a group consisting of: materials represented by chemical formulae A1, A2, A3, and A4 indicated in materials represented by chemical formulae B1, B2, B3, B4, and B5 indicated in materials represented by chemical formulae C1 and C2 indicated in materials represented by chemical formulae D1 and D2 indicated in
