The research field is packaging of power electronics. The drivers are performance, volume or weight per cost depending on the application. The goal is reached by investigations on different concepts of the electrical, mechanical and thermal design such as single and double sided die attach, single and double sided cooling, materials with minimized or matched coefficient of thermal expansion (CTE). By use of intelligent setups and application relevant choice of the electrical and thermal interconnections the bill of material can be minimized.
Work is done on joining technologies as well. There is a long experience in silver sintering as an alternative to the state of the art. Meanwhile a process is established to manufacture multichip power modules with high yield. Especially a selective sintering process brings high advantages to electronic packaging. The chip sizes meet the power electronics requirements. While the sintering improvements are ongoing the soldering technology is still covered from state to the art up to new high performance or high temperature materials.
