Abstract

A spin chuck rotatably holds a semiconductor wafer, while resist is dropped on a surface of the semiconductor wafer through a resist application nozzle and thus applied thereon, and before the resist applied on the wafer dries, a cleaning liquid is supplied through a bevel cleaning nozzle to a portion of the wafer located at a peripheral portion thereof in a vicinity of a beveled portion to remove the resist adhering to the beveled portion. Thereafter, a film of the resist that is formed on the surface of the wafer is dried.
