- the cavity 8 is closed with a hermetic and thermally conductive cover 12.
- a hermetic and thermally conductive cover 12 In the manufacture of the integrated circuit module 3, it is already hermetically sealed with the cover 12, so that lower requirements for the mounting and mounting of the integrated circuit module 3 with the mainboard 2 must be made in the subsequent processing stages.
- the thermally conductive cover 12 also ensures good heat dissipation of the heat energy from the semiconductor chip 9 to the motherboard 2.
- the thermal coupling can with thermally conductive contact material 13a, 13b between the semiconductor chip 9 and the cover 12 and between the cover 12 and an electrically insulating Layer 14 of Haupt ⁇ board 2 can be improved. With the thermally conductive contact material 13a, 13b and height variations of the mounted semiconductor chip 9 can be compensated.
- the sealing between the cover 12 and the multilayer Suspray substrate 4 can be done with a hermetic seal 15, which is spielmik arranged on the peripheral edge of the cover 12.
- the motherboard 2 which is also poor thermal conductivity at the same time, to a heat sink 16 of the motherboard 2 can be improved with thermal vias 17, which is adjacent to the cover 12 through the electrically insulating layer 14 of the motherboard 2 extend to the heat sink 16.
- the integrated circuit module 3 is electrically connected by means of a direct contact 18 with the motherboard 2 and is substantially directly on the motherboard 2.
- FIG. 2 shows a second embodiment of the multichip circuit module 1, in which the integrated circuit module 3 does not rest directly on the substrate 2, but electrically by using a ball-grid array (BGA) 19 electrically with the main board 2 is contacted. This results in a distance between the integrated circuit module 3 and the main board 2, which is balanced with the heat-conductive contact material 13b.
- BGA ball-grid array
- FIG. 3 shows a third embodiment of the multi-chip circuit module 1, in which the hermetically sealed integrated circuit module 3 is embedded in a recess 20 of the main board 2, in particular in the electrically insulating layer 14.
- This has the advantage that the heat generated by the semiconductor chip 9 via the electrical contact material 13a, 13b and the cover 12 is guided directly into the heat sink 16 of the motherboard 2.
- the thermal impedance of the electrically insulating layer 14 of the motherboard and the thermal impedance of the thermal vias 17 in the path between the semiconductor chip 9 and heat sink 16 are thus eliminated.
- the integrated circuit module 3 can be connected via a parallel field coupling 21 a or a field coupling by overlapping 21 b to the motherboard 2.
- the parallel field coupling 21 a the zu ⁇ ordered electrical connections of the integrated circuit module 3 and the motherboard 2 are directly opposite with their ends, without touching and produce a direct electrical contact.
- the Field coupling by overlapping 21 b the terminals of the integrated circuit module and the motherboard 2 overlap, but without touching.
- FIG. 4 shows a fourth embodiment of the multichip
- Detect circuit module 1 wherein the integrated circuit module 3 is in turn recessed in a recess of the electrically insulating layer 14 of the motherboard 2.
- the electrical contacting of the integrated circuit module with the mainboard 2 takes place here by means of a bonding connection 22 or by means of direct contacting by overlapping connections 23 and optionally a direct contact 18.
- the illustrated with a thermally conductive cover 12 hermetically sealed multi-chip circuit modules 1 are due to the hermeti- see encapsulation of the embedded semiconductor chips 9 in the multi-layer Trä ⁇ gersubstrat 4 robust against environmental influences.
- the encapsulation already carried out prior to assembly of the integrated circuit module 3 on a carrier makes possible a simple storage, further processing and test possibility, for example burn-in. Due to the simultaneous good thermal dissipation use of power semiconductors in the integrated circuit module 3 is possible.
- the multi-chip circuit module 1 can also be produced inexpensively due to the compatibility with standard industrial processes. In addition, due to the freedom of design of the interface between the integrated circuit module 3 and the motherboard 2, application-adapted transitions are possible.
