The present invention provides a tunneling field effect transistor and a method for fabricating the same which refer to a field effect transistor logic device and circuit in a CMOS ultra-large integrated circuit (ULSI). The inventive concept of the invention lies in that, in a case of an N-type transistor, a side portion of a doped source region adjacent to an edge of the control gate is further implanted with P+ impurities on a basis of the doped source region being initially doped N&#x2212; impurities, so that the initial N&#x2212; impurities in the implanted portion are completely compensated by the P+ impurities, and in a case of a P-type transistor, a side portion of the doped source region adjacent to an edge of the control gate is implanted with N+ impurities on a basis of the doped source region being initially doped P&#x2212; impurities, so that the initial P&#x2212; impurities in the implanted portion are completely compensated by the N+ impurities. In the transistor, the source region is implanted twice with different doping concentrations, such that a large current characteristic of the MOSFET can be effectively combined to increase an on-state current of the transistor, and also, the threshold adjustment for the MOSFET portion and the TFET portion of the transistor can be achieved in a self-adaptive way.

Disclosed herein is a method for fabricating a complementary tunneling field effect transistor based on a standard CMOS IC process, which belongs to the field of logic devices and circuits of field effect transistors in ultra large scaled integrated (ULSI) circuits. In the method, an intrinsic channel and body region of a TFET are formed by means of complementary P-well and N-well masks in the standard CMOS IC process to form a well doping, a channel doping and a threshold adjustment by implantation. Further, a bipolar effect in the TFET can be inhibited via a distance between a gate and a drain on a layout so that a complementary TFET is formed. In the method according to the invention, the complementary tunneling field effect transistor (TFET) can be fabricated by virtue of existing processes in the standard CMOS IC process without any additional masks and process steps.
