    Abstract: A plating method includes holding a substrate, supplying a plating liquid L1, supplying a conductive liquid L2 and applying a voltage. In the holding of the substrate, the substrate is held. In the supplying of the plating liquid L1, the plating liquid L1 is supplied onto the held substrate. In the supplying of the conductive liquid L2, the conductive liquid L2, which is different from the plating liquid L1 supplied on the substrate, is supplied onto the plating liquid L1. In the applying of the voltage, the voltage is applied between the substrate and the conductive liquid L2.

    Abstract: An electrolytic treatment apparatus 1 (1A) configured to perform an electrolytic treatment on a target substrate includes a substrate holder 10 and an electrolytic processor 20. The substrate holder 10 includes an insulating holding body 11 configured to hold the target substrate and an indirect negative electrode 12 disposed within the holding body 11. A negative voltage is applied to the indirect negative electrode 12. The electrolytic processor 20 is disposed to face the substrate holder 10 and configured to apply a voltage to the target substrate and an electrolyte in contact with the target substrate.

    Abstract: An electrolytic treatment apparatus of the present disclosure includes a common electrode and a counter electrode that are disposed such that the treatment liquid is interposed therebetween. A first wiring and a second wiring are connected to the common electrode, a capacitor is provided in the first wiring. Copper ions are moved to the counter electrode side by forming an electric field in the treatment liquid when the capacitor is charged without connecting the first wiring and the second wiring to each other, and the copper ions moved to the counter electrode side are reduced by applying a voltage between the common electrode and the counter electrode when the capacitor is discharged by connecting the first wiring and the second wiring to each other.
