Abstract
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.
