Abstract:
A substrate processing apparatus for processing a substrate to be processed by supplying processing gas and solvent vapor to the substrate, the apparatus comprising:a processing container for accommodating the substrates therein; a processing-gas supplier for supplying a processing-gas into the processing container, the processing-gas chemically processing the substrates accommodated in the processing container; a solvent-vapor generator for generating the solvent vapor to be supplied into the processing container; a first valve interposed in a supply pipeline that supplies the solvent vapor generated in the solvent-vapor generator into the processing container; a second valve interposed in a discharge pipeline branching from the supply pipeline on the upstream side of the first valve; a first pressure researcher for researching a pressure of the solvent vapor in the solvent-vapor generator; and a controller for controlling respective opening/closing operation of the first valve and the second valve on the basis of a detection signal outputted from the pressure researcher.
