Term · Industrial and trades · MLC-T-IND-004588

A brittle intermetallic compound, specifically gold-aluminum intermetallic (AuAl2), that forms at the interface between gold wire bonds and aluminum bond pads in semiconductor devices. This compound can lead to increased electrical resistance and mechanical weakness, causing bond failures over time. It is a reliability concern in microelectronics packaging.
