Patent ID: 8623146

Claim:
A substrate processing method, comprising: a solidifying step of solidifying a liquid to be solidified by supplying a cooling gas, which has a temperature lower than a solidification point of the liquid to be solidified, from a nozzle to a surface of a substrate to which the liquid to be solidified is adhering while holding the substrate substantially horizontally and rotating the substrate about a vertical axis; and a melting step of melting and removing the liquid solidified by the solidifying step, wherein the solidifying step includes: an initial solidifying step of supplying the cooling gas from the nozzle, which is arranged above an initial position distant from the rotation center of the substrate toward the outer edge of the substrate, to the initial position so as to solidify the liquid to be solidified in an initial region extending from the initial position to a rotation center of the substrate; and a nozzle moving step of relatively moving the nozzle toward the outer edge of the substrate while supplying the cooling gas from the nozzle after the initial solidifying step.
