Abstract
In a substrate treating unit, a removal liquid supplying mechanism supplies a removal liquid to the surface of a substrate. In order to retain the removal liquid on the surface of the substrate for a fixed time, a spin chuck is operated to spin the substrate at such a low speed as to retain the removal liquid on the substrate, or spins the substrate intermittently, or temporarily stops spinning of the substrate. Thus, treatment with the removal liquid progresses without a further supply of the removal liquid, thereby restraining consumption of the removal liquid.
