ABSTRACT:
A method for high resolution maskless plating with an immersion, exchange or like plating bath is described. Preferential plating results from exposing those regions where plating is sought to an energy beam to increase the plating rate and the resulting plating thickness is several orders of magnitude greater than is possible by standard immersion techniques.
