Cu pillar bump with eutectic SnPb was annealed and the micro structures were observed by scanning electron microscopy. Both of Cu6Sn5 and Cu3Sn grew following parabolic rate law at 120 and 150degC. At 165degC, Cu6Sn5 growth was stagnated while Cu3Sn growth rate was increased after 160 hour when all Sn was consumed. Kirkendall void was formed because of different diffusivities of Cu and Sn. The activation...
