Abstract :
An analytical threshold voltage model for double-gate MOSFETs with localized charges is developed. From the 2-D Poisson´s equation with parabolic potential approximation, a compact threshold voltage model is derived. The proposed model is then verified with a 2-D device simulator. The model can be used to investigate hot-carrier-induced device degradation for various device dimensions and various charge distributions.
