Patent ID: 8094455

Claim:
A high-density integrated circuit module structure, comprising: a substrate 20 at least has an inner surface 201 and an outer surface 202 with a plurality of outer pads 203 and a plurality of adapter pads 204 wherein the outer pads 203 electrically connect to the adapter pads 204 and the inner surface 201 of the substrate 20 is equipped with an electronic device 205 at least electrically connecting the outer pads 203 and the adapter pads 204 ; a heat sink 30 at least with a plurality of heat conductors 31 wherein the heat sink 30 is installed on end planes of the adapter pads 204 on the substrate 20 and the heat conductors 31 contact the adapter pads 204 and have a non-flat structure 311 at least; the substrate 20 has the outer pads 203 electrically contacting the adapter pads 204 ′ on another substrate 20 ′ by heat conductors 31 to construct the integrated circuit module with a reversely-staggered contacting high-density stack structure.
