Additives for electroplating copper that are optimal for forming fine wiring on semiconductor package substrates.
We have developed two new products, "Topluchina NSV ADV" and "Topluchina NSV LV," as plating additives for via filling with high current density fine patterns. Topluchina NSV ADV maintains excellent via filling performance while achieving high film thickness uniformity in fine wiring. Topluchina NSV LV is a copper sulfate plating additive compatible with fine patterns and large-diameter vias, enabling through-hole filling by plating copper inside the through holes.
