## Abstract

In multilevel 3D integrated packaging, three major microstructures are viable due to the application of low volume of solders in different sizes, and/or processing conditions. Thermodynamics and kinetics of binary compounds in Cu/Sn/Cu low volume interconnection is taken into account. We show that current crowding effects can induce a driving force to cause excess vacancies saturate and ultimately cluster in the form of microvoids. A kinetic analysis is performed for electromigration mediated intermetallic growth using multi-phase-field approach. Faster growth of intermetallic compounds (IMCs) in anode layer in the expense of shrinkage of cathode IMC layer in shown. This work paves the road for computationally study the ductile failure due to formation of microvoids in low volume solder interconnects in 3DICs.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
