Abstract:
A power semiconductor module includes a direct copper bonded (DCB) substrate having a ceramic substrate, a first copper metallization bonded to a first main surface of the ceramic substrate and a second copper metallization bonded to a second main surface of the ceramic substrate opposite the first main surface. The power semiconductor module further includes a power semiconductor die attached the first copper metallization, a passive component attached the first copper metallization, a first isolation layer encapsulating the power semiconductor die and the passive component, a first structured metallization layer on the first isolation layer, and a first plurality of electrically conductive vias extending through the first isolation layer from the first structured metallization layer to the power semiconductor die and the passive component. An integrated power module and a method of manufacturing the integrated power module are also provided.
