This paper reviews the development of various structures of Tunnel Field Effect Transistors. In order to enhance the on-state current and decrease the short-channel effects, various non-planar structures were designed. Among all these non-planar structures, DGDM-GeOI Vertical TFET structure not only provide the benefits of performance enhancement but also fulfill the requirement of reduced footprint of the device.

This short note presents the simulation result on the effect of channel engineering i.e., non-uniform channel doping on short channel effects (SCE) in nano Fin-FET devices using Silvaco TCAD tool. The nano Fin-FET structures were generated using DEVEDIT and the effect of channel doping concentration has been studied. The optimum doping concentration profile has been observed to considerably improve the SCE in general and drain induced barrier lowering (DIBL) in particular.

Virtual Fabrication of sub-40nm Bulk MOSFET is carried out under channel engineering and source drain engineering process. These structures enable more aggressive device scaling in nano-scale region because of their ability to control short channel effects. How ever during scaling the junction depth should also be scaled down, which increases parasitic resistance so silicidation technique has been applied to reduce their effects on device. Analog performance has been measured in terms of gm, gds ,Av ,fT and fmax .The simulation result predict that gm is 3.75ms for engineered MOSFET as compared to nonengineered MOSFET with gm of 2.9ms for similar gate length, similarly Av for engineered device is 17.5db and for non-engineered device is 6.96db,fT is 146GHz and for non-engineered fT is 65GHz,fmax is 299GHz for engineered device and for nonengineered device fmaxis 170GHz and a comparison of an engineered device is done with a non engineered device to investigate the improved performance of an engineered device as compared to a non engineered device. Silvaco TCAD Tool is used for Virtual fabrication and simulation. ATHENA process simulator is used for virtual fabrication and ATLAS device simulator is used for device characterization.
