Patent ID: 8756802

Claim:
A method of making carbon nanotube contact structures on a first electronic device, comprising: growing a plurality of first carbon nanotube columns on a mandrel; applying an electrically-conductive adhesive to ends of the first columns distal from the mandrel; transferring the first columns to the first electronic device by bringing the ends of the first columns distal from the mandrel into contact with first terminals of the first electronic device; separating the mandrel from the first columns to leave the first columns attached to the first terminals of the first electronic device by the electrically-conductive adhesive; depositing an electrically-conductive material onto the first columns; and reusing the mandrel to grow a second plurality of carbon nanotube columns on the mandrel, wherein the applying an electrically-conductive adhesive comprises bringing a stamping tool into contact with the ends of the first columns distal from the mandrel to transfer the electrically-conductive adhesive from the stamping tool onto the ends of the first columns, wherein the electrically-conductive adhesive is applied to the stamping tool using a technique selected from the group consisting of coating and patterning.
