WebJan 12, 2015 · In this study, copper filling in through-silicon via (TSV) by pulse periodic reverse electroplating and low alpha solder bumping on Cu filled TSVs was investigated. The via diameter and depth of ... WebCopper Electroplating for 3D TSV 3D integration of integrated circuits requires die-to-die interconnection by TSV with high-density, high-aspect-ratio, and through-chip connections. This results in reduced resistive capacitive delay or RC delay, lower power consumption, improved form factor, heterogeneous integration, and lower manufacturing cost.
