Abstract:
A liquid processing apparatus of the present disclosure holds and rotate a substrate in a substrate holding unit, ejects an etching liquid while moving a main nozzle of a main nozzle unit between a first position where the etching liquid reaches a center of the substrate and a second position closer to a peripheral side of the substrate than the first position, and then, ejects the etching liquid to the substrate from a sub nozzle provided at a third position closer to the peripheral side of the substrate than the first position at an ejection flow rate higher than that from the main nozzle.
