摘要:The present invention relates to methods and apparatus for plating aconductive material on a substrate surface in a highly desirable manner. The invention
removes at least one additive adsorbed on the top portion of the workpiece more thanat least one additive disposed on a cavity portion, using an indirect external influence,thereby allowing plating of the conductive material take place before the additive fullyre-adsorbs onto the top portion, thus causing greater plating of the cavity portionrelative to the top portion.
