The present invention relates to a power semiconductor chip module, comprising a substrate having a top side and a bottom side; at least one first power semiconductor device attached to the top side of the substrate; at least one first conductive structure thermally and electrically connecting the first power semiconductor device to the top side of the substrate; at least one second power semiconductor device attached to the bottom side of the substrate; and at least one second conductive structure connecting the second power semiconductor device to the bottom side of the substrate.

Power semiconductor chip module

The present invention relates to a stackable power module, comprising a module body having a top side and a bottom side provided with top and bottom contact pads, each of the top contact pads electrically connected to a corresponding bottom contact pad; at least one power semiconductor device embedded in the module body, at least one conductive structure connecting the power semiconductor device to a respective top and/or bottom contact pad, wherein the at least one conductive structure has a thermal capacity sufficient to take up an amount of heat generated during a switching cycle of the at least one power semiconductor device without increasing temperature above a critical threshold.

Stackable power module

A circuit carrier assembly includes a plurality of substrates directly secured together by an electrically conductive securing substance. In one example, the securing substance is a conductive epoxy. In another example, the electrically conductive securing substance is solder. Still another example includes a combination of solder and conductive epoxy. A non-conductive epoxy provides further mechanical connection and thermal conductivity between the substrates while also electrically isolating selected portions of the substrates in one example. The electrically conductive securing substance not only mechanically secures the substrates together and provides thermal conductivity between the substrates, which increases the thermal capacitance of the assembly, but also establishes at least one electrically conductive path between the substrates.
