Abstract:
1. An article comprising: a substrate having a first surface and a second surface; a single material metallic seed layer embedded in the substrate, wherein the single material metallic seed layer is substantially planar to the substrate second surface; an anisotropic carbon nanotube (CNT) array disposed upon and directly contacting the metallic seed layer, wherein the CNT array extends through a portion the substrate and extends above the substrate first surface; and an electrical bump directly coupled to the substrate and in direct contact with the single metallic seed layer, wherein the electrical bump extends through a portion of the substrate and extends above the substrate first surface, and wherein the CNT array is impregnated within the electrical bump; wherein the CNT array extends above the substrate first surface beyond the electrical bump.
