Analysis of SCEs in nanoscale FinFET with high-k gate dielectric

Abstract

We derive a three-dimensional (3-D) analytical model of scale length for nanoscale SOI tri-gate FET (SOI-FinFET) and discuss its significance. This work takes into account the difference in permittivity between the fin (channel) and the gate insulator, and thus permits this model accurate for the analysis of SCEs in nanoscale FinFET with high-k gate dielectric. Based on the theory, we analyze the effects of geometrical dimensions and materials on the SCEs in nanoscale FinFET.
