Failure Mechanism Models for Material Aging Due to Inter-Diffusion

J. Li and A. Dasgupta


This tutorial illustrates design situations where material aging due to inter diffusion in some components can compromise system performance over time, thereby acting as a wearout failure mechanism.  Micro-structural diffusion mechanisms, continuum diffusion models, and inter-diffusion analysis techniques are presented to design against such failures.  An example illustrates the application of the mechanisms, models, and techniques in electronic packaging.
