Abstract:
A substrate processing apparatus for processing at least a substrate to be processed held in a processing vessel with a processing gas and a solvent vapor fed to the substrate, the apparatus comprising:a processing gas feed system for feeding the processing gas into the processing vessel; a solvent vapor feed system for feeding the solvent vapor into the processing vessel; a nitrogen gas feed pipe for feeding nitrogen gas into the processing vessel, wherein a nitrogen gas flow rate control valve is inserted in said nitrogen gas feed pipe; and a central controller for controlling the feed of the processing gas and the solvent vapor to be fed into the processing vessel, said central controller controlling the flow rate of nitrogen gas flowing through said nitrogen gas feed pipe so as to feed nitrogen gas, the processing gas and the solvent vapor to remove a resist on the substrate to be processed and etch a metal on the substrate-to-be-processed, and controlling the flow rate of nitrogen gas flowing through said nitrogen gas feed pipe so as to feed the processing gas and the solvent vapor to remove a resist on the substrate-to-be-processed but not etch a metal on the substrate-to-be-processed, wherein said central controller controls said processing gas feed system to feed the processing gas into the processing vessel to pre-pressurize the interior of the processing vessel before processing the substrate-to-be-processed and controls said processing gas feed system and said solvent vapor feed system to feed the processing gas and the solvent vapor respectively into the processing vessel to process the substrate-to-be-processed.
