Abstract:
A method for forming uniform dendrites on a circuitized substrate, comprising the following steps:a. providing circuitized substrate comprising:a substrate having a top surface;circuitization disposed on, and attached to, the top surface of the substrate, the circuitization having a top surface, a side wall and an edge where the top surface and the sidewall meet;b. applying photoresist to the substrate to cover the circuitization and the top surface of the substrate;c. patterning the photoresist to expose at least a portion of the top surface of the circuitization upon which the dendrites will be formed;d. forming, by additive process, a plurality of dendrites, in the presence of the photoresist, on the exposed top surface of the circuitry;wherein the dendrite height is 50% greater or lower than the average dendrite height.
