Abstract: A method for manufacturing a carbon nano tube transistor and a carbon nano tube transistor by the same are provided to improve a semiconductor property by removing a metallic property inside a carbon nano tube channel inside a carbon nano tube transistor. In a carbon nano tube transistor, a carbon nano tube channel(30) is formed between a source electrode and a drain electrode(20). A gate electrode is formed in one side of the carbon nano tube channel. The carbon nano tube channel is formed on a substrate(10). The source electrode and the drain electrode are electrically connected to both ends of the carbon nano tube channel. A metallic property inside the carbon nano tube channel is removed by applying a stress voltage between the source electrode and the drain electrode.

Abstract: A carbon nanotube transistor having a deformation electrode is provided to increase the work function of a metal and to effectively induce hole doping by using an SU-8 negative photoresist on an electrode of the carbon nanotube transistor. An alignment marker is formed on a SiO2/Si substrate(10). A pattern of liquid catalyst is manufactured using a PMMA(polymethylmethacrylate) layer on the SiO2/Si substrate that is insulated by a SiO2 layer. The PMMA layer is removed by an acetone solution. A single walled carbon nanotube(14) is grown at CH4 and H2 atmosphere during 10 minutes in a furnace of 900 ‹C. An electrode(12) is formed by performing photolithography and thermal evaporation on the carbon nanotube. The electrode is connected to the carbon nanotube to configure a carbon nanotube transistor and then an SU-8 negative photoresist(16) is coated on the carbon nanotube transistor to form an insulating layer.
