A simplified model is presented for the degradation of the conducting properties of Al stripes subjected to electromigration. Such a model has been used in order to investigate the role of grain boundaries in the be- havior of the temperature coefficient of resistance (TCR).

Abstract
A simplified model is presented for the degradation of the conducting properties of Al stripes subjected to electromigration. Such a model has been used in order to investigate the role of grain boundaries in the be- havior of the temperature coefficient of resistance (TCR). The results obtained by means of two dimensional simulations allow us to give a sim- ple interpretation of the experimentallyobserved fluctuations of the TCR during electromigration.File in questo prodotto:
