Beschreibung
Zusammenfassung:	A package structure for power devices includes a heat dissipation insulating substrate, a plurality of power devices, a heat dissipation baseplate, and a thermal interface layer. The heat dissipation insulating substrate has a first surface and a second surface which are opposite to each other, and the power devices are coupled to the first surface of the heat dissipation insulating substrate. The heat dissipation baseplate is disposed at the second surface of the heat dissipation insulating substrate, wherein at least one of a surface of the heat dissipation baseplate and the second surface of the heat dissipation insulating substrate has at least one plateau, and the plateau is at least disposed within a projected area of the plurality of power devices. The thermal interface layer is disposed between the second surface of the heat dissipation insulating substrate and the surface of the heat dissipation baseplate.
