Abstract

A special mode has a second rinsing process which supplies a rinsing liquid to a substrate while holding and rotating the substrate with a spin chuck under operating conditions different from those in a first rinsing process in a normal mode. In the second rinsing process, a processing cup is cleaned with the rinsing liquid flown off from the rotating substrate. In the second rinsing process in which the substrate is held by the spin chuck, the rinsing liquid flown off from the substrate is less prone to collide with chuck members. The provision of a mechanism designed specifically for the cleaning of the cup is not required in the special mode. The special mode is a mode executable when a substrate is present inside a chamber, and can be executed in the middle of lot processing.
