Electromigration behavior in aluminum wires for power base-station applications

In this paper, a study on electromigration in aluminum bond wires as used in power base station application is presented. Electromigration is shown to occur in three phases and is accompanied by bamboo formation. From accelerated tests, a lifetime model has been determined, based on Black's equation. This enables the prediction of the lifetime of products under high temperature and current conditions.
