Abstract:
1. A microelectronic assembly, comprising: a heat spreader having a first major surface and a second major surface opposite the first major surface; at least one die located with respect to the first major surface of the heat spreader and thermally coupled to at least a portion of the heat spreader; at least one other die located with respect to the second major surface of the heat spreader and thermally coupled to at least a portion of the heat spreader; an opening in the heat spreader, the opening located in a region of the heat spreader between the at least one die and the at least one other die; an insulator located in the opening; and electrically conductive material located in an electrically insulated through hole in the insulator, wherein the insulator electrically isolates the electrically conductive material and the heat spreader from each other.
