Abstract

We investigated the impact of fin length (T_fin) on the threshold voltage (V_th) modulation by back bias (V_b) for independent double-gate (IDG) tunnel fin field-effect transistors (tFinFETs). It was found that V_th can be tuned by V_b for IDG tFinFETs regardless of T_fin, which can be explained by the back-gate-effect model of IDG FinFETs. For IDG tFinFETs, the slope (back-gate-effect factor (γ)) of V_th with respect to V_b increases with thinning T_fin. This means that T_fin thinning is effective for tuning V_th by V_b for IDG tFinFETs. Furthermore, it was demonstrated that this back-bias-effect is consistent with the results of device simulation using an advanced nonlocal band-to-band model.
