Abstract

Cu<inf>6</inf>Sn<inf>5</inf> intermetallic is an important compound formed during reaction between Sn-rich interconnects and copper metallization. The full elastic constants of Cu<inf>6</inf>Sn<inf>5</inf> were quantified experimentally by Resonant Ultrasound Spectroscopy (RUS). The single crystal elastic properties were modeled by density functional theory. A mesoscale polycrystalline model, incorporating the single crystal constants was compared to the experimental results, yielding excellent agreement.
