Abstract:
1. A liquid treatment apparatus of continuously performing a plating process on a plurality of substrates, the liquid treatment apparatus comprising: a temperature controlling container configured to accommodate a plating liquid; a temperature controller configured to control a temperature of the plating liquid accommodated in the temperature controlling container; a holding unit configured to hold the substrates one by one at a predetermined position; a nozzle having a supply hole through which the temperature-controlled plating liquid accommodated in the temperature controlling container is discharged to a processing surface of the substrate held by the holding unit; a pushing unit configured to push the temperature-controlled plating liquid accommodated in the temperature controlling container toward the supply hole of the nozzle; and a supply control unit configured to control a timing when the plating liquid is pushed by the pushing unit, wherein the temperature controller is configured to control the temperature of the plating liquid accommodated in the temperature controlling container based on the timing when the plating liquid is pushed by the pushing unit, wherein the temperature controller is configured to perform a cooling control of the plating liquid accommodated in the temperature controlling container if the plating liquid is not pushed toward the supply hole of the nozzle for a predetermined time period.
