Abstract:
1. A package comprising: a substrate having a first surface and a second surface; a metallic seed layer embedded in the substrate proximate the substrate second suface; an anisotropic carbon nanotube (CNT) array disposed upon the metallic seed layer; an electrical bump impregnated within the CNT array, extending above the substrate first surface, in contact with the metallic seed layer, and touching the substrate; and a microelectronic device including a bond pad, wherein the bond pad is coupled to the electrical bump, wherein the microelectronic device is a flip chip, the package further including a mounting substrate with a mounting substrate bond pad on a first surface of the mounting substrate, and wherein the metallic seed layer is in contact with the mounting substrate bond pad.
