Abstract
A plating method and apparatus using contactless electrode is described. In one embodiment an inductive element is placed proximally to a substrate and a moving electromagnetic field generates an emf in the substrate to plate the surface. In another embodiment, a conductive plate is used, so that the conductive plate and the wafer, separated by a dielectric material, operate as two plates of a capacitor when voltage is applied to the conductive plate. The resulting electrostatic field impresses a charge potential on the substrate to plate the surface of the substrate.
