Abstract:
1. A liquid processing method using a liquid processing device which comprises a substrate holding unit configured to horizontally hold a substrate and to rotate the substrate around a vertical axis, a chemical liquid nozzle configured to supply a chemical liquid to a surface of the substrate, a hydrophobic gas nozzle configured to supply a hydrophobic gas to the surface of the substrate, and a rinsing liquid nozzle configured to supply a rinsing liquid to the surface of the substrate, the method comprising: supplying the chemical liquid from the chemical liquid nozzle to the surface of the substrate which is held and rotated by the substrate holding unit to perform a liquid processing; supplying the rinsing liquid from the rinsing liquid nozzle to the surface of the substrate while rotating the substrate to replace the chemical liquid by the rinsing liquid; hydrophobizing the substrate by alternately repeating supply of the hydrophobic gas for hydrophobizing the surface of the substrate to the surface of the substrate from the hydrophobic gas nozzle while rotating the substrate and supply of the rinsing liquid to the surface of the substrate while rotating the substrate after the hydrophobic gas is supplied; and drying the substrate by removing the rinsing liquid while rotating the substrate.
