Abstract
Electroplating methods and systems employing ultrasonic energy to enhance electroplating processes. The electroplating methods involve sweeping a plating surface with ultrasonic energy having an area of maximum ultrasonic energy density while simultaneously performing electroplating. The systems include movement apparatus providing relative movement between an ultrasonic energy source and a cathode while the ultrasonic energy source and the cathode are located within a plating tank.
