| Zusammenfassung: | The module (1) has a number of sub-modules (2) with at least one semiconducting chip (3) attached to the top of an electrically insulating, heat conducting substrate (6) with a thermal expansion coefficient matching that of the chip. One sub-module (2) directly in the substrate has a cooler (7) of a good thermal conductor. The cooler is embedded in the underside (6b) of the substrate. |
