Abstract:
1. A liquid processing apparatus comprising: a substrate holding member configured to rotate along with a substrate held thereon in a horizontal state; a rotary cup configured to surround the substrate held on the substrate holding member and to rotate along with the substrate; a rotation mechanism configured to integrally rotate the rotary cup and the substrate holding member; a process liquid supply mechanism configured to supply a process liquid onto an upper surface of the substrate; a cleaning liquid supply mechanism configured to supply a cleaning liquid onto an outer surface of the rotary cup, the process liquid supply mechanism and the cleaning liquid solution mechanism sharing a liquid delivery nozzle configured to deliver the process liquid and the cleaning liquid and a supply section configured to supply the process liquid and the cleaning liquid to the liquid delivery nozzle; a nozzle transfer mechanism configured to transfer the liquid delivery nozzle to place the liquid delivery nozzle at a first position above the substrate held on the substrate holding member and to place the liquid delivery nozzle at a second position above the outer surface of the rotary cup; and a control section configured to control an operation of the apparatus, wherein the control mechanism includes a non-transitory storage medium that stores a program, which, when executed, causes the control section to control the apparatus to conduct a sequence, the sequence including: placing the liquid delivery nozzle at the first position and delivering the process liquid onto the upper surface of the substrate from the liquid delivery nozzle at the first position to perform a liquid process on the substrate, and placing the liquid delivery nozzle at the second position and delivering the cleaning liquid onto the outer surface of the rotary cup from the liquid delivery nozzle at the second position to perform a cleaning process on the rotary cup.
