Understanding and improving the uniformity of electrodeposition
WebOct 1, 2024 · Herein, the base electrolyte without leveler was used as blank. A widely used and commercially available leveler for copper electroplating, Janus Green B (JGB), was used as the comparison. It could be seen from Fig. 2a that the copper electrodeposition was inhibited. Conclusion. WebJun 15, 2015 · The leveler holds back the plating at the knee and allows the bottom plating to proceed without pre-mature closure of the via due to dog boning (over-plating at the knee). The plating dynamics in the bottom of the hole are very different than those on the board surface. Eventually as the hole fills, the plating dynamics even out. WebAug 19, 2024 · Levelers exhibiting high microvia-filling power and wide operating-concentration ranges are required for the development of additives in copper super-conformal electroplating. In this study, a novel structure based on triphenylmethane (TPM-1) was synthesized and investigated as a leveler for microvia-filling electroplating. research kitchen
