Abstract:
A method of manufacturing a cooling structure of a multichip module on which a plurality of integrated circuit devices are mounted, comprising the steps of:arranging a heat sink having a plurality of recess portions so that a surface of the heat sink at which the plurality of recess portions are formed faces upward;supplying the plurality of recess portions with low melting point metal material;melting the low melting point metal material;inserting at least a part of each of a plurality of thermal conduction blocks into each of the plurality of recess portions of the heat sink via the melted low melting point material;placing a heat insulating sheet on the plurality of thermal conduction blocks;placing the multichip module on the heat insulating sheet so that the plurality of integrated circuit devices of the multichip module are located in to correspond with the plurality of thermal conduction blocks;solidifying the low melting point metal material;removing the heat insulating sheet;providing thermal compounds on the plurality of thermal conduction blocks andconnecting the integrated circuit devices of the multichip module to the thermal compounds respectively.
