Abstract

The ageing of the metallization layer (aluminum reconstruction) which is due to power cycling on dies of power semiconductor modules results in the redistribution of the current lines in the metallization layer but also in the elementary cells of the power dies (MOSFET or IGBT) with a critical risk of failure when local current density or local temperature reach a critical value. The paper reports on the estimation of the local degradation of the aluminum sheet resistance due to power cycling which is evaluated by means of an eddy current sensor. First results of experimental data on power dies are presented for the first time.
