Patent ID: 8262898

Claim:
A nanotube position controlling method comprising: placing on a substrate having a plurality of facing electrodes, a flow path pattern which has a plurality of flow paths along a facing direction of the plurality of the facing electrodes, wherein leading end portions of the plurality of facing electrodes are tapered off to a point, wherein the substrate also has a plurality of integrated electrodes, wherein a plurality of thin wires fuses are connected between the plurality of the facing electrodes and the integrated electrodes, wherein the plurality of thin wires fuses are provided so as to have a one-to-one correspondence relation with the plurality of the facing electrodes, and wherein a width of the plurality of thin wires fuses and a width of the plurality of integrated electrodes are different, applying a voltage between the plurality of the facing electrodes, guiding a flow of a nanotube dispersed solvent in one direction through a tunnel-like path formed by at least one of the plurality of the facing electrodes and one of the plurality of flow paths, to successively and respectively suspend a plurality of nanotubes between a plurality of the facing electrodes, without intersection, and after the solvent is dried, peeling off the flow path pattern from the substrate.
