Abstract

Power module packaging is driven by the ever increasing demand for higher power densities, reliability improvements and further cost reduction. The known reliability limitations of traditional solder joints and bond wires are limiting a significant power density increase, enabled by higher junction temperatures and the future utilization of wide bandgap devices. Silver sintering today has started to replace the solder joint from chips to DBC substrates, leaving one major reliability bottleneck: The bond wire interface on the chip top side.
