    Abstract: PURPOSE: A tunneling field effect transistor having the FINFET structure of an independent dual gate and a fabrication method thereof are provided to increase the driving current without the loss of a separate area by forming a vertical dual gate structure which is electrically separated from both sides of a semiconductor pin. CONSTITUTION: A semiconductor substrate (10) includes a semiconductor pin (14) at a constant height. A p+ region (62) and an n+ region (64) are formed at both sides of the semiconductor substrate. The semiconductor pin is formed between the p+ region and the n+ region. A first gate (52) is formed between one side of the semiconductor pin and the n+ region. A second gate (54) is formed between the other side of the semiconductor pin and the p+ region. The material of the first gate is different from that of the second gate.
