METHOD FOR LOCALLY ENHANCING ELECTROPLATING RATES Abstract A method for high resolution maskless electro- plating is described. Preferential plating results from exposing those regions where enhanced plating is sought to a collimated energy beam. Such exposure can produce an enhancement in the plating rate of 103, which is sufficient to eliminate the necessity of masking the surface.
