Abstract

The structure with vertical channel is attractive due to suppression of the short-channel effect, where the shape of silicon fin determines the device performance. In this work, the DC characteristics of single-fin FinFET are simulated, which shows a better immunity against fluctuation induced by random dopant than that of tri-gate and quasi-planar fin shapes. Increasing the number of silicon fins of FinFET can further improve the performance. Examining the fluctuation induced by random dopant in CMOS inverter and SRAM circuits with triple-fin structure shows that the fluctuation of intrinsic gate delay and SNM in triple-fin FinFET are smaller and larger, respectively, than that of others due to higher driving current.
