  • Publication number: 20220105535
    Abstract: A substrate processing apparatus includes a processing tank, a holder, an organic solvent supply, a drainage port, a gas supply, and an exhaust port. The processing tank stores an aqueous layer. The holder holds a substrate. The organic solvent supply supplies an organic solvent onto the aqueous layer to form a liquid layer of the organic solvent. The drainage port discharges the aqueous layer from a bottom wall of the processing tank and causes the liquid layer of the organic solvent to descend from above the substrate to below the substrate. The gas supply supplies a gas of a water repellent agent to the liquid layer from above the processing tank while the liquid layer descends. The exhaust port is exposed on a side wall of the processing tank by the descending of the liquid layer and discharges the gas of the water repellent gas.
