Abstract
Fin-type field-effect transistors (FinFETs) are vulnerable to the random interface trap (RIT)-induced reliability issue caused by the bias temperature instability and hot carrier injection, which adversely affects the device performance. In this study, the electrical characteristic fluctuations induced by RITs are analyzed and a comparison is performed between the negative-capacitance FinFETs (NC-FinFETs) and their FinFET counterparts using technology computer-aided design (TCAD) simulation. The number and position of the trapped charges are randomly distributed at the silicon/silicon oxide (Si/SiO2) interface following the Poisson statistics recorded for the assembly of 200 fabricated transistors. The results demonstrate that the electrical characteristic dispersions of both the NC-FinFETs and FinFETs increase with the increase in the RIT concentration. However, the off-state currents demonstrate an opposite trend for the NC-FinFETs and FinFETs. Additionally, some NC-FinFETs with RITs exhibit steeper subthreshold swing (SS) characteristics than those without traps. Electrical parameter fluctuations are simultaneously produced by both the devices by the position uncertainty under the same RIT concentrations. This issue can be overcome by the partial suppression ability of the NC-FinFET which suppresses RIT-induced reliability due to the amplified electrostatic potential.
