Abstract:
1. An apparatus for processing a substrate, comprising: a processing head for processing the substrate by bringing the substrate into contact with a processing liquid supplied to and held in the processing head, said processing head having a substrate holder for holding the substrate, said processing head being arranged to hold the substrate with said substrate holder while a surface to be processed of the substrate is facing upwardly, and to define a processing bath for holding the processing liquid with said surface to be processed of the substrate and a seal ring for sealing an outer peripheral region of said surface to be processed of the substrate; a heat-insulating tank surrounding said substrate holder in a water-tight manner, for holding the processing liquid held in said processing head together with said substrate holder at a predetermined temperature with a thermal medium; and a processing liquid supplying system for supplying the processing liquid at a predetermined temperature to said processing head.
