Patent ID: 7439731

Claim:
A method for forming an electrical probe device, comprising: forming an arrangement of nanotubes on a first substrate; providing a second substrate having a pre-arranged electrical contact pattern corresponding to a pattern on a sample to be tested; and transferring at least some of the nanotubes from the first substrate to the second substrate, thereby forming the probe device comprising the second substrate and the transferred nanotubes, including: applying a conductive material to one or both ends of the nanotubes, and/or to the second substrate in areas to which the nanotubes are to be contacted, aligning the first and second substrates, moving the substrates together such that the ends of the nanotubes contact and adhere to the areas of the second substrate, activating the conductive material to facilitate adhesion of the ends of the nanotubes to the areas, and moving the substrates apart such that the nanotubes separate from the first substrate and remain attached to the areas of the second substrate.
