Abstract:
1. A substrate processing apparatus comprising: a chamber; a substrate holding mechanism, disposed in the chamber, that horizontally holds a substrate to be processed; a cleaning-liquid supply unit that supplies a cleaning liquid containing hydrofluoro ether onto a substrate to be processed horizontally held by the substrate holding mechanism to form a liquid film of the cleaning liquid containing hydrofluoro ether on the substrate to be processed; a gas supply unit that supplies a gas into the chamber, the gas being configured to prevent moisture from being adhered to a substrate to be processed when a cleaning liquid containing hydrofluoro ether is supplied onto the substrate to be processed; and a control unit that controls the cleaning-liquid supply unit and the gas supply unit such that the gas is supplied from the gas supply unit into the chamber, before the cleaning liquid containing hydrofluoro ether is supplied from the cleaning-liquid supply unit onto the substrate to be processed, horizontally held by the substrate holding mechanism, and the liquid film of the cleaning liquid containing hydrofluoro ether is formed on the substrate to be processed.
