ABSTRACT:
A method for high resolution maskless electroless plating is described. Preferential plating results from exposing those regions where plating is sought to an energy beam to increase the plating rate by a factor of 10.sup.3 to 10.sup.4. This enhancement is sufficient to make masking unnecessary.
