Abstract
The junction between Au and Al in a current-carrying contact for application to integrated circuits is considered. The conductivity of the compound is identified by means of a field-inversion technique.
The simulation of the growth process of the Au-Al compound relies on the transient field analysis of the current flow through the junction. Results of the identification are compared with measurements.
