Method for removing metallic nanotube

A method for removing a metallic nanotube which is formed on a substrate in a first direction, the method comprising:

• forming a plurality of conductors in a second direction crossing the first direction, the conductors electrically contacting the metallic nanotube, respectively;
• forming an insulating layer to cover the conductors;
• patterning the insulating layer to expose a first conductor or a first group of conductors out of the plurality of the conductors in a first region and to expose a second conductor or a second group of conductors, different from the first conductor or the first group of conductors, out of the conductors in a second region different from the first region;
• forming a first voltage-applying electrode on the insulating layer in the first region and a second voltage-applying electrode on the insulating layer in the second region, so that the first voltage-applying electrode electrically contracts the first conductor or the first group of conductors via the patterned insulating layer, and the second voltage-applying electrode electrical contacts the second conductor or the second group of conductors via the patterned insulating layer;
• applying different voltages to the first and second voltage-applying electrodes, respectively, to burn out the metallic nanotube;
• and
• removing the voltage-applying electrodes, the insulating layer and the conductors.
