Abstract

A cleaning apparatus and a cleaning method for restricting an occurrence of water marks on a surface of a object to be processed are provided. The cleaning apparatus is constructed so as to dry wafers W, which have been rinsed by DIW in a drying chamber 42, in a cooling system. Thus, the reaction between, for example, IPA, DIW etc. and silicon in surfaces of the wafers W is inactivated to cause the surfaces to be oxidized with difficulty, so that it is possible to restrict the occurrence of the water marks on the surfaces.
