Analysis of the Effect of Field Enhancement at Fin Corners on Program Characteristics of FinFET Split-Gate MONOS

Abstract

The effect of field enhancement at Fin corners on program characteristics of FinFET Split-gate metal oxide nitride oxide silicon (SG-MONOS) is analyzed. The program characteristics using source-side injection (SSI) are found to be insensitive to the variation of the curvature radius at Fin corners, which shows the robustness of FinFET SG-MONOS to Fin shape variation inthe fabrication process.
