Abstract:
1. A substrate for electronic packaging components and integrated circuit components comprising: a core plate containing a Group VIB metal from the periodic table of the elements and/or an anisotropic material, having a first major surface and a second major surface and a plurality of openings extending, at least partially, from the first major surface to the second major surface; a Group IB metal from the periodic table of the elements or other high thermally conductive material filling at least a portion of the space encompassed by at least some of the openings; and optionally, a layer containing a Group IB metal from the periodic table of the elements or other high thermally conductive material disposed over at least a portion of the first major surface and at least a portion of the second major surface and wherein the ratio of the diameter of the openings to the thickness of the plate is from 0.75 to 1.5 and the diameter of the openings are up to 25 mils.
