Highly integrated power modules based on copper thick-film-on-DCB for high frequency operation of SiC semiconductors—Design and manufacture

The Publisher's final version can be found by following the DOI link. This paper encompasses the design and the manufacture of a full-SiC module based on copper thick-film. Both DC-link capacitors as well as gate drives are implemented onto the substrate in order to minimise parasitic inductances. Thus, the module is especially suitable for high-frequency operation such as inductive energy transfer and inverter systems for renewable energies and electrical vehicles. In order to maintain high mechanical strength of the module's substrate, a Direct Copper Bond (DCB) provides the basis for multiple thick-film layers. The used thick-film dielectric insulates the gate-drive islands and also works as solder-stop material. The heat-spreading capabilities of DCB substrates are investigated by simulations.
