Abstract :
In power electronics, the development of new IGBT power modules allows them to switch kV and kA during us. However, such components need to be cooled and ceramic materials like AlN and Al2O3 are used as an interface between the electronic devices (the chips) and the cooling. Such materials have to present very well known electrical and thermal characteristics since the reliability of the inverters these components are used in is strongly dependant on them. In order to increase the knowledge of the physical mechanisms involved during aging of these materials, we present in this paper the very first results obtained in this field. Finally, all these results are discussed and analyzed in view of power electronics applications
