摘要 A method of plating which improves the uniformity of a plated coating thickness without changing the flow velocity of a feed plating solution. An aperture at a center of a mesh anode electrode of a plating apparatus produces an electric field density distribution between the mesh anode electrode and a wafer that is lower in the central portion of the wafer than at the edge portion of the wafer.
