发明名称 Substrate plating device
摘要 The present invention relates to a substrate plating apparatus for plating a substrate in a plating bath containing plating solution. An insoluble anode is disposed in the plating bath opposite the substrate. The substrate plating apparatus comprises a circulating vessel or dummy vessel provided separate from the plating bath, with a soluble anode and a cathode disposed in the circulating vessel or dummy vessel. An anion exchange film or selective cation exchange film is disposed between the anode and cathode and isolates the same, wherein metal ions are generated in the circulating vessel or dummy vessel by flowing current between the soluble anode and the cathode therein, and the generated metal ions are supplied to the plating bath. The substrate plating apparatus can also comprise an ion exchange film or neutral porous diaphragm disposed between the substrate and anode in the plating bath, wherein the ion exchange film or neutral porous diaphragm divides the plating bath into a substrate region and an anode region.
