Substrate holder, apparatus for plating, method of plating and storage medium

Abstract

One object of the present disclosure is to suppress or prevent a plating solution from entering a sealed space of a substrate holder and to detect entry of the plating solution promptly. There is provided a substrate holder configured to hold a substrate and cause the substrate to come into contact with a plating solution and to be plated. The substrate holder comprises an internal space configured to place an outer circumferential portion of the substrate therein such as to be sealed from outside of the substrate holder, in a state that the substrate is held by the substrate holder; a first passage configured to connect the outside of the substrate holder with the internal space and to introduce a liquid into the internal space; and a detector placed in the internal space and configured to monitor an electric current flowing in the liquid or an electric resistance of the liquid during plating in a state that the liquid is introduced into the internal space and thereby detect a leakage of the plating solution to the internal space.
