Patent ID: 8252167

Claim:
An electroplating method for plating a workpiece having a surface to be plated using a plating solution, the electroplating method comprising: holding a plating solution in a plating tank; arranging an anode in the plating tank so as to be immersed in the plating solution held in the plating tank; holding the workpiece by a holder and bringing the surface of the workpiece into contact with the plating solution held in the plating tank; arranging a fixing plate, having an opening therein, so as to divide an interior of the plating tank into an anode compartment accommodating the anode and a workpiece compartment accommodating the workpiece held by the holder; injecting the plating solution toward the surface of the workpiece held by the holder to supply the plating solution into the plating tank from a plurality of injection nozzles formed on a ring-shaped nozzle pipe which is fixed to the fixing plate in the plating tank so as to be immersed in the plating solution held in the plating tank, the nozzle pipe being shaped to extend along an outer profile of the workpiece; and applying a plating voltage between the anode and the workpiece to perform electroplating on the surface of the workpiece.
