Abstract

A hole is formed on a liquid film of a low surface tension liquid which covers an entire region of an upper surface of a substrate, and a central portion of the upper surface of the substrate is exposed. The hole in the liquid film of the low surface tension liquid is expanded up to an outer circumference of the substrate. Discharge of hot water is stopped before formation of the hole in the liquid film of the low surface tension liquid. After the liquid film of the low surface tension liquid has been expelled from the upper surface of the substrate, hot water is supplied again to a lower surface of the substrate. A liquid adhering to the substrate is shaken off after stoppage of discharge of the hot water.
