Abstract
A cooling gas discharge nozzleis arranged above an initial position P(Rin) distant from a rotation center P(0) of a substrate W toward the outer edge of the substrate W and supplies a cooling gas to the initial position P(0) of the rotating substrate W to solidify DIW adhering to an initial region including the initial position P(Rin) and the rotation center P(0). Following formation of an initial solidified region FR, a range to be solidified is spread toward the outer edge of the substrate W and all the DIW (liquid to be solidified) adhering to a substrate surface Wf is solidified to entirely freeze a liquid film LF.
