Abstract:
A cooling structure of a multichip module on which a plurality of integrated circuit devices are mounted, said cooling structure comprising:a plurality of thermal conduction members that are respectively provided on the plurality of integrated circuit devices of the multichip module;a heat sink being provided on the multichip module, the heat sink having a plurality of recess portions which are located at positions corresponding to the plurality of thermal conduction members;a projection portion formed on the thermal conduction members, being received in each of the plurality of recess portions of the heat sink and having a shape operative to absorb dispersion in heights and slopes of heat-radiation surfaces of the integrated circuit devices; anda connecting material contained in said plurality of recess portions that connects an interior of the recess portions of the heat sink to a part of the projection portion received in the interior of the recess portions, for preventing the thermal conduction members from moving relative to the heat sink.
