Abstract

The past few years have seen organic substrates become a popular alternative to ceramics substrates for power modules. The design flexibility of organic substrates allows for a high level of integration with the cooling system and gate driver circuitry. Although organic substrates have many benefits, the intrinsic features of the thin dielectric cause thermal and common-mode (CM) current issues. This work aims to address these concerns by modeling and optimizing multi-layer organic substrates for a wirebond-less 1.7 kV SiC MOSFET power module. The geometry and layout are optimized to minimize the module's maximum temperature and high capacitive coupling to the baseplate. The simulation and optimization of multi-layer organic substrate design enable a 30 dB reduction in CM noise while achieving a maximum temperature of less than 175 °C.
