We review recent physics-based, analytical DC models for amorphous silicon (a-Si), polysilicon (poly-Si), and organic thin film transistors (TFTs), developed for the design of novel ultra high-resolution, large area displays using advanced short-channel TFTs. In particular, we emphasize the modeling issues related to the main short-channel effects, such as self-heating (a-Si TFTs) and kink effect (a-Si and poly-Si TFTs), which are present in modern TFTs. The models have been proved to accurately reproduce the DC characteristics of a-Si:H with gate lengths down to 4 μm and poly-Si TFTs with gate lengths down to 2 μm. Because the scalability of the models and the use of continuous expressions for describing the characteristics in all operating regimes, the models are suitable for implementation in circuit simulators such as SPICE.

Effect Of Doping

MOSFET have been scaled down over the past few years in order to give rise to high circuit density and increase the speed of circuit. But scaling of MOSFET leads to issues such as poor control gate over the current which depends on gate voltage. Many short channel effects (SCE) influence the circuit performance and leads to the indeterminist response of drain current. These effects can be decreased by gate excitation or by using multiple gates and by offering better control gate the device parameters. In Single gate MOSFET, gate electric field decreases but multigate MOSFET or FinFET provides better control over drain current. In this paper, different FET structures such as MOSFET, TFET and FINFET are designed at 22nm channel length and effect of doping had been evaluated and studied. To evaluate the performance donor concentration is kept constant and acceptor concentration is varied.
