Abstract
An apparatus includes substrate holders each configured to hold a substrate, a first nozzle provided for each substrate holder and for discharging a first processing liquid to the substrate at a first position, a second nozzle provided to be shared by the substrate holders and for discharging a second processing liquid to the substrate at a second position, a third nozzle provided for each substrate holder and for discharging a third processing liquid to the substrate at a third position while the first and second processing liquids are not supplied to the substrate, first to third standby parts for respectively allowing the first to third nozzles to wait outside a substrate holding region, a turning mechanism for turning the first nozzle between the first standby part and the first position, and a linear motion mechanism for linearly moving the third nozzle between the third standby part and the third position.
