Design Device for Subthreshold Slope in DG Fully Depleted SOI MOSFET

In this paper, we discuss how a short channel effects can be suppressed and how a threshold voltage fluctuation can be minimized and better control of subthreshold slope by the impact of the back gate bias and control of gate work function of a fully depleted SOI (Silicon-On-Insulator) MOSFET. The fluctuation in the threshold voltage and subthreshold slope are due to short channel effects. The Back gate voltage plays a significant role on the threshold voltage and thin buried oxide is used to suppress the short-channel effects and is used to keep a low value of the subthreshold slope are described in this paper. It is shown that how short channel effects can be suppressed in order to improve subthreshold slope.
