Packaging for power semiconductors based on the 3D printing technology Selective Laser Melting

In this paper a new packaging technique based on Selective Laser Melting is presented which tries to replace solder or sinter layers, respectively bond wires. Following the intended contact geometry and concept, simulations show the influence of the contact geometry on the thermo-mechanical stress the device is committed to. First investigations on the constraints of the production process are represented. Finally the feasibility of the proposed packaging technique is shown.
