Abstract
A method for washing and drying a substrate includes the steps of (a) disposing a substrate on a spin chuck such that a surface to be treated faces upward, (b) applying a washing solution from a first nozzle to the surface of the substrate while rotating the substrate disposed on the spin chuck so as to cleanse the surface, and (c) blowing a gas from a second nozzle against the surface while rotating the substrate and moving the second nozzle above the substrate in a radial direction from a central portion toward a peripheral portion of the substrate, thereby drying the surface of the substrate.
