Abstract:In recent semiconductor designs, the major key factors: Competent device simulations, precise device characterization, well power optimization, new architectural design and cost-effective fabrication drives the designers attention towards multi gate transistors as an alternative to MOSFET. Non planner device structures are a competitive edge over planner devices. Silicon-on-Insulator (SOI) FinFETs are hopeful among variety of multi-gate structures as they have simple fabrication, Superior gate control, lower subthreshold leakage and minimized susceptibility to process variations. Low leakage memory cells play a significant role of power consumption in the recent VLSI Systems. In this study, Ultra-low Voltage Asymmetric Short Gate (UVASG) FinFET is modeled with TCAD tools for low leakages and FinFET based SRAM has been proposed as a substitute for the bulk devices.
