1. A method of fabricating a semiconductor device comprising:
forming a sacrificial material layer on a substrate;
disposing at least one nano-line having semiconductor characteristics on the sacrificial material layer;
forming a mask pattern on a portion of the nano-line and the sacrificial material layer;
forming spaced apart source and drain electrodes at respective sides of the mask pattern and surrounding respective portions of the nano-line at the respective sides of the mask pattern;
removing the mask pattern and at least a portion of the sacrificial material layer below the mask pattern and the at least one nano-line to form an opening exposing a portion of the nano-line between the source and drain electrodes; and
forming a gate electrode surrounding the exposed portion of the nano-line.
