Abstract:
A semiconductor package structure comprising:a printed board having a first surface on which a plurality of first heat-conductive patterns are provided and a second surface on which a plurality of second heat-conductive patterns are provided, said printed board having heat-conductive through holes connecting said first and second heat-conductive patterns;a multi-chip module having a plurality of semiconductor packages and being provided on said first surface of said printed board;a plurality of heat-conductive supporting members provided on said first heat-conductive patterns;a heat radiator structure having at least two heat radiation fins and at least a heat radiation groove defined by said heat radiation fins, said heat radiator structure being provided on said multi-chip module; anda plurality of heat conductivity plate-shaped members fixed to said heat-conductive supporting members and inserted into said heat radiation groove so that said heat conductivity plate-shaped members are in contact with upper surfaces of said heat radiation fins,wherein a first heat transfer route is formed for transferring a heat generated in said multi-chip module through said heat radiator structure to atmosphere surrounding said heat radiator structure,wherein a second heat transfer route is formed for transferring said heat through said heat radiator structure, said heat conductivity plate-shaped members, said heat-conductive supporting members and said first heat-conductive patterns to said printed board and also to said through holes which are heat-conductive to said second heat-conductive patterns, andwherein a third heat transfer route is formed for transferring said heat to said printed board.
