Abstract:
1. A semiconductive device comprising a die, said device having: (a) at least one defined hot-spot area lying in a plane on said die; (b) cooling means comprising a plurality of nanotube means composed of a first heat conducting material and extending in a plane different than the plane of said hot-spot area and outwardly from the plane of said hot-spot area, said nanotube means operatively associated with said hot-spot area to decrease any temperature gradient between said hot-spot area and at least one other area on said die defined by a temperature lower than said hot-spot area; (c) said nanotube means being substantially surrounded by a matrix material comprised of a second heat conducting material extending away from said nanotube means and toward said die to directly contact said die on said other area on said die defined by a temperature lower than said hot-spot area, so that said matrix material is operatively associated with and in heat conducting relation with said other area; (d) the heat conductivity of said first heat conducting material being greater than the heat conductivity of said second heat conducting material; (e) the distal ends of said nanotube means comprising said first heat conducting material, and positioned for direct contact with a medium comprising a fluid heat exchange medium.
