A unified FinFET reliability model including high K stack dynamic threshold, hot carrier injection (HCI), and negative bias temperature instability (NBTI) has been developed and verified by experimental data. The FinFET-based circuit performances are simulated and compared under these reliability issues by HSPICE simulator after the inclusion of the presented model.
