Abstract
Nozzle arms for holding discharge heads are caused by a pivotal driving part to move between a processing position above a substrate and a standby position outside a processing cup surrounding a substrate. When the nozzle arms having cleaned a substrate is placed at the standby position, a cleaning solution is ejected from a shower nozzle toward the nozzle arms arranged obliquely downward of the shower nozzle. The three nozzle arms are caused to move up and down such that the nozzle arms cut across a jet of a cleaning solution discharged obliquely downward, thereby cleaning the three nozzle arms in order. Then, a nitrogen gas is ejected from a drying gas nozzle and sprayed on the nozzle arms to remove the cleaning solution attached to the nozzle arms, thereby drying the nozzle arms.
