Abstract:
1. An integrated circuit package comprising: a substrate having a first surface and a second surface; a die pad area, disposed on said first surface, said die pad area having dimensions suitable to mount an integrated circuit thereon; a first thermally conductive structure disposed at least partially around said die pad area on said first surface; a second thermally conductive structure underlying said first thermally conductive structure and disposed on said second surface; a first plurality of thermally conductive bars on said first surface that radiate outwardly from the die pad area and that are thermally coupled to said first thermally conductive structure; a second plurality of thermally conductive bars on said second surface underlying the first plurality of bars and that are thermally coupled to said second thermally conductive structure; and a plurality of thermally conductive vias, at least one of the vias coupled between said first and second thermally conductive structures for providing thermal conductivity from the first surface of the substrate to the second surface of the substrate, wherein each of the plurality of thermal bars conduct thermal energy from the die pad area to an associated one of said first thermally conductive structure and said second thermally conductive structure.
