Abstract:
1. A liquid processing apparatus comprising: a substrate retaining part that retains a substrate in a horizontal position and rotates the substrate; a first processing liquid supply nozzle that supplies a first processing liquid to the substrate retained by the substrate retaining part; a second processing liquid supply nozzle that supplies a second processing liquid to the substrate retained by the substrate retaining part; a liquid receiving cup disposed to surround the substrate retained by the substrate retaining part in radial directions of the substrate such that an upper end of the liquid receiving cup is positioned above the substrate, so as to receive the processing liquid having been supplied from the first processing liquid supply nozzle or the second processing liquid supply nozzle to the substrate; a first tubular outer cup including an upper opening and disposed around the liquid receiving cup, the first tubular outer cup being vertically movable between a lifted position at which an upper end of the first tubular outer cup is positioned above the liquid receiving cup, and a lowered position positioned lower than the lifted position; and a second tubular outer cup including an upper opening and disposed around the liquid receiving cup and outside the first tubular outer cup, the second tubular outer cup being vertically movable between a lifted position at which an upper end of the second tubular outer cup is positioned above the liquid receiving cup, and a lowered position positioned lower than the lifted position; when the first processing liquid supply nozzle supplies the first processing liquid to the substrate, the first tubular outer cup is positioned at its lifted position and the second tubular outer cup is positioned at its lowered position; and when the second processing liquid supply nozzle supplies the second processing liquid to the substrate, the first tubular outer cup is positioned at its lowered position and the second tubular outer cup is positioned at its lifted position.
