Plating apparatus, air bubble removing method, and storage medium that stores program to cause computer in plating apparatus to execute air bubble removing method

Abstract

A plating module includes a plating tank, a substrate holder, an elevating mechanism, an anode, an ionically resistive element, a supply pipe, and a bypass pipe. The substrate holder is for holding a substrate Wf with a surface to be plated Wf-a facing downward. The elevating mechanism is for moving up and down the substrate holder. The anode is disposed inside the plating tank so as to face the substrate Wf held by the substrate holder. The ionically resistive element is disposed between the anode and the substrate Wf. The supply pipe is for supplying a process liquid stored in a reservoir tank from a lower side of the ionically resistive element to the plating tank. The bypass pipe is for discharging the process liquid supplied to the plating tank via the supply pipe from the lower side of the ionically resistive element to the reservoir tank.
