We present a comparative study of the electrical characteristics of different 1200V commercial SiC power MOSFETs at cryogenic temperatures down to 77 K. As compared to conventional silicon power MOSFETs, SiC MOSFETs show very different operating characteristics at low temperatures which is due to unique material and design parameters used in SiC MOSFETs. Of particular interest is a non-linear mixed triode/pentode-like I-V characteristic exhibited by all SiC MOSFETs at 77 K, which is demonstrated to be due to short channel effects in the constituent JFET.

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.
