Abstract:
1. A liquid processing apparatus comprising: a first processing area and a second processing area that are aligned such that substrates that are horizontally placed are respectively processed by a chemical liquid from a nozzle; a first individual nozzle and a second individual nozzle that are provided individually to correspond to the first processing area and the second processing area; a first individual-nozzle transfer mechanism and a second individual-nozzle transfer mechanism that are respectively configured to transfer the first individual nozzle and the second individual nozzle between waiting positions and chemical-liquid discharging positions in the respective processing areas; a common nozzle that is used in common in the first processing area and the second processing area, the common nozzle being configured to supply the chemical liquid onto the substrates; a common-nozzle transfer mechanism configured to transfer the common nozzle among a waiting position, a chemical-liquid discharging position in the first processing area and a chemical-liquid discharging position in the second processing area; and a control unit configured to control the first individual-nozzle transfer mechanism, the second individual-nozzle transfer mechanism and the common-nozzle transfer mechanism; wherein the control unit is configured to control the respective nozzle transfer mechanisms such that a time period in which the common nozzle is engaged with the process in each processing area is shorter than a time period in which the individual nozzle is engaged with the process in each processing area.
