This paper presents design issues of a novel three-dimensional packaging ap
proach for power modules. Solder interconnections are implemented on power
devices (insulated gate bipolar transistors and diodes) to obtain vertical
interconnections for the proposed multi-layer packaging technique. Issues r
elated to materials selection and processing, electrical and thermo-mechani
cal aspects of implementing the new packaging concept are discussed. (C) 20
