Abstract:

Metallic alloy that forms an ordered solid-state compound between two or more either metallic or non-metallic elements are called Intermetallics. One of the most common wire bonding technology involving Cu wire interconnections is the thermosonic bonding technique. Effects of Cu free air ball and bonding temperature with high temperature storage (HTS) treatment on Cu-Al bonding interface are unclear due to varying observations and inconsistencies in the bonding parameters. A quantitative stress analysis via statistical modelling could close the research gap. Microstructural characterizations were focused on Cu-Al IMC crystallographic system, compositional classification and ball bond mechanical strength analyses. The bonding temperature was found to affect the thickness of the initial IMC layer formed at the bonding interface. The amount of the initial IMC formation in turn influences the saturation thickness of the IMC after HTS treatment. In the theoretical part, a stress model was proposed by coupling of both thermal misfit and diffusion induced stresses. It was found that the stress developed by interfacial Cu-Al IMC generally increased with the bonding temperature. The influence of forming gas supply was found to be less significant to affect the interfacial stress development, as the oxide layers did not hinder much the interdiffusion of Cu and Al atoms in the Cu-Al IMC formation. This report addressed the research gaps and presented a better understanding of the fundamental of interfacial stress formation of thermosonic Cu-Al interconnection. References 1. T.
