Abstract: A high-temperature wide-bandgap power module and a preparation method thereof is provided in the present application. In the high-temperature wide-bandgap power module, SiC power chips are arranged in the cavity, and bonding wires are used to establish electrical connections. An ultrathin composite conformal coating consists of inorganic film and Parylene-HT film is arranged on the surface of the circuit to provide long-term reliable insulation while only imposing minor thermo-mechanical stresses on bonding joint at high-temperatures, which prolongs the module's life time. In addition, the hermetic sealing adopted in the present application blocks the external water, oxygen and chemical pollution, thereby alleviating the thermal degradation of the conformal coating and safeguards the internal circuit. Overall, the hermetic sealing and conformal coating ensure the long-term 250 degrees high-temperature working capability of the wide-bandgap power module.
