SUBSTRATE CLEANING METHOD, SUBSTRATE CLEANING APPARATUS AND STORAGE MEDIUM FOR SUBSTRATE CLEANING
摘要:
A method for cleaning a surface of a substrate having a circuit pattern formed thereon, includes: forming a liquid film on the surface by feeding a cleaning solution onto the center of the surface while rotating the substrate with the substrate kept horizontal; forming a dry region by discharging gas to the center while moving a position of feed of the cleaning solution on the surface by a distance from the center toward the periphery of the substrate with the substrate being rotated; moving the position of feed of the cleaning solution on the surface toward the periphery at a speed equal to a speed at which the dry region is expanded toward the periphery while rotating the substrate; and controlling temperature of the cleaning solution to form the liquid film such that the temperature becomes higher than process atmosphere temperature on the surface during feed of the cleaning solution.
