Copper pillar electroplating tutorial - DuPont
2016-12-8 Copper pillars are electroplated over a Cu seed layer at the base, with photoresist defining the diameter of the pillar. A nickel diffusion barrier between the pillar and the solder cap limits formation of a copper-tin intermetallic layer at the interface or prevents formation of microvoids. Excessive intermetallic growth and microvoids can both negatively affect reliability.
