Patent ID: 8809208

Claim:
A method for forming a structure, comprising: providing a semiconductor structure having an electrically and thermally conductive layer disposed on one surface of the semiconductor structure; providing an electrically and thermally conductive heat sink; providing a unit comprising: a electrically and thermally conductive carrier layer; a plurality of electrically and thermally conductive nano-tubes, a first portion of the plurality of nano-tubes having proximal ends disposed on a first surface of the carrier layer and a second portion of the plurality of nano-tubes having proximal ends disposed on an opposite surface of the carrier layer; a plurality of heat conductive tips disposed on distal ends of the plurality of nano-tubes, the tips having an adhesive material with a bonding material coating the adhesive material; providing a sandwich structure comprising the provided unit disposed between the provided heat sink and provided semiconductor structure with the plurality of heat conductive tips on the first portion of the plurality of nano-tubes positioned in contact with the conductive layer and with the plurality of heat conductive tips on the second portion of the plurality of nano-tubes being positioned in contact with the heat sink; applying heat to the sandwich structure to simultaneously bond: (1) the plurality of heat conductive tips on the first portion of the plurality of nano-tubes to the conductive layer; and (2) the plurality of heat conductive tips on the second portion of the plurality of nano-tubes to the heat sink; and wherein the tips on the distal ends of the first portion of the plurality of nano-tubes are thermo-compression bonded to the conductive layer simultaneously as the tips of the second portion of the plurality of nano-tubes are thermo-compression bonded to the heat sink.
