Hot carrier generation and reliability of BT(body-tied)-Fin type SRAM cell transistors (W/sub fin/=20/spl sim/70 nm)
2005
In this paper, we fabricated a BT-FinFET SRAM device with the smallest cell size of 0.46 /spl mu/m/sup 2/. And a hot carrier generation mechanism in the FinFET is thoroughly evaluated by measuring the I/sub sub/ of the BT-FinFET for various Si fin widths (20/spl sim/70 nm). For the first time, we revealed the mechanism of improved hot carrier immunity of sub 50 nm fin type MOSFETs.
