Abstract
The research focuses on the design and analysis of a Gate Stacked Double Metal Surrounding Gate Nanowire MOSFET (DMSG-NWFET) using In1−xGaxAs as the channel material. The performance of this MOSFET has been evaluated through simulations conducted using the silvaco ATLAS TCAD tool. The study examines the impact of Channel Length (L) and the ratio of L1/L on various DC characteristics, including Drain-Induced-Barrier-Leakage (DIBL), OFF-current (Ioff), ON-current (Ion), Subthreshold Slope (SS), and threshold voltage (Vth). In-depth analysis has been performed by varying the indium portion (1−x) in the In1−xGaxAs channel. Additionally, we investigate the radio frequency (RF) performances by considering the variation of the 'In' fraction and incorporating the cut-off frequency (fT). The investigation demonstrates that the In1−xGaxAs based Gate Stacked Double Metal Surrounding-Gate Nanowire MOSFET exhibits superior DC and RF performance when an optimized fraction of In (Indium). We believe that the proposed device structure holds significant promise for low power VLSI applications.
