    • 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.

    • The present invention provides a compound tunneling field effect transistor integrated on a silicon substrate, and a method of fabricating the same. The present invention enables to increase tunneling efficiency with an abrupt band slope by forming a source region with a material having a bandgap of at least 0.4 electron volts (eV) narrower than that of silicon, to increase a driving current (ON current) by forming a channel region with a material having almost no difference in lattice constant from a source region having a high electron mobility at least 5 times higher than that of silicon, and to simultaneously increase ON/OFF current ratio to a great amount by forming a drain region with a material having a bandgap wider than or equal to that of a channel region material to restrain OFF current to the utmost. Furthermore, the present invention enables to easily form tunneling field effect transistors having various threshold voltages in accordance to the circuit designs by adding a specific material (e.g. aluminum) have an electron affinity less than that of a source region material in the process of forming a channel region.
