Abstract: A transistor with a carbon nanotube channel and a method of manufacturing the same. At least two gate electrodes are formed on a gate insulating layer formed on a carbon nanotube channel and are insulated from each other. Thus, the minority carrier may be reduced or prevented from flowing into the carbon nanotube channel. Accordingly, it is possible to reduce or prevent a leakage current that is generated when both the majority carrier and the minority carrier flow into the carbon nanotube channel. Therefore, characteristics of the transistor may not be degraded due to the leakage current.
