Methods for cleaning surfaces are provided. Such a method may comprise contacting a surface with a fluid comprising a compound of Formula I for a period of time; and removing the fluid from the surface, thereby providing a cleaned surface. Vapor phase degreasing systems for cleaning a surface of a component are also provided. Such a system may comprise a boil sump comprising liquid comprising a compound of Formula I; and a holder configured to hold a component in a vapor formed from the liquid.

A substrate treating method, liquid and apparatus are provided which can reduce the amount of sublimable substance used for the drying of a substrate while reducing the collapse of pattern. The substrate treating method includes a step of supplying a liquid to the pattern-formed surface of the substrate, a step of solidifying the liquid on the pattern-formed surface to form a solidified body and a step of subliming the solidified body so as to remove it from the pattern-formed surface. The substrate treating liquid includes a molten sublimable substance and a solvent, the freezing point of the sublimable substance being higher than the freezing point of the solvent. When the sublimable substance and the solvent are separated, the sublimable substance is settled and in the solidification step, the settled sublimable substance is solidified to have a height equal to or higher than the height of a pattern.
