Abstract

Apparatus and system, as well as fabrication methods therefor, may include a thermal intermediate structure comprised of a plurality of carbon nanotubes some of which have organic moieties attached thereto to tether the nanotubes to at least one of a die and a heat sink. The organic moieties include thiol linkers and amide linkers.

Claims (8)

1. A process:

coating at least one surface of least one of a heat sink and of a die with a metal;

oxidizing carbon nanotubes ropes in sulfuric and nitric acids, whereby the carbon nanotubes ropes are cut into a plurality of short carbon nanotubes with open ends having carboxyl linkages attached thereto;

treating at least one end of at least some of a plurality of carbon nanotubes by applying organic moieties thereto; and

tethering one end of the at least some of the carbon nanotubes of the plurality of carbon nanotubes to the metal.

2. The process of claim 1 wherein the metal is selected from the group consisting of gold and gold alloys.

3. The process of claim 2 , wherein the treating the at least one end of some of the plurality of nanotubes comprises forming an amide based linkage thereon.

4. The process of claim 2 , wherein the treating the at least one end of some of the plurality of nanotubes comprises forming an amide based linkage and a thiol based linkage thereon.
