The tunneling junction in the SAA-TFET is divided laterally and vertically with respect to the channel direction which provides a relatively large tunneling junction area. An n+ pocket design is also introduced around the source to enhance tunneling rates and improve the device characteristics. In addition, the gate and n+ pocket region also overlap in the vertical and the lateral directions resulting in an enhanced electric field and, in turn, the ON-state current of the SAA-TFET is highly increased compared with the conventional TFET. Promising results in terms of DC (I ON , I OFF , ON/OFF current ratio and SS) and analog (cutoff frequency) performance are obtained for low (V DD = 0.5 V) and high (V DD = 1 V) supply voltages.
