Abstract :
The analysis of failure mechanism due to electromigration requires precise knowledge of the resistivities and theit time dependences as a function of current density and stripe temperature. This is possible with the aid of Matthiessen´s rule. The results show a different behaviour in the changes of the residual resistivities PR and the crose-sectional areas A for pure Al and Al-Cu samples.
