Abstract:
1. A liquid processing apparatus comprising; a substrate holder for holding a substrate horizontally; a nozzle unit in which a plurality of processing-liquid nozzles are provided in a common support integrally, the plurality of processing-liquid nozzles being connected to respective processing-liquid supply passages to each supply the substrate held by the substrate holder with a processing liquid; a standby unit having a plurality of solvent reservoirs each storing a solvent for the processing liquid, the plurality of solvent reservoirs being arranged to allow tips of the plurality of processing-liquid nozzles of the nozzle unit to dip into the solvent, and a drain part arranged to receive processing liquid discharged from at least one of the plurality of processing-liquid nozzles; suck means for sucking each processing-liquid nozzle of the nozzle unit; and transfer means for transferring the nozzle unit between a first position over the plurality of solvent reservoirs, a second position over the drain part, and a third position over the substrate to supply the substrate with the processing liquid, wherein the plurality of processing-liquid nozzles of the nozzle unit, and the plurality of solvent reservoirs and the drain part of the standby unit are arranged on a straight center line passing through a rotational center of the substrate.
