R. J. von Gutfeld, et al., have described a new method of laser-enhanced electroplating and maskless pattern generation where localized heating at the cathode (a metal film) by a focused laser beam causes increased local convection and hence faster electroplating *. They also quote the earlier work of M. P. Drake, who reported that if an ultrasonic wave is focused onto a cathode in a plating bath, a plated pattern can be generated (by moving the focused spot on the cathode surface). These previous studies are concerned with the enhancement of plating by using an external device to focus some form of energy on the cathode.
