  • Aging comparative analysis of high-performance FinFET and ...

    2020-3-20 · Different aging factors including NBTI, PBTI and HCI affect the re-liability and performance of digital devices in modern systems. NBTIrefers to the generation of interface traps and positive oxide chargein metal-oxide silicon structure in p-channel MOS devices, sincethey operate with negative gate-to-source voltage (Vgs =−VDD)and elevated temperature. The threshold voltage (Vth) increasingand on-current (Ion) decreasing due to NBTI has a huge impact onthe performance of PMOS transistors whilst PBTI shows a negligibledegradation in NMOS devices[1,2]. Hot Carrier Injection (HCI) re-fers to a carrier injected from the conducting channel to the gateoxide and cause a shift in Vthvalue. FinFET behavior is thesame as CMOS transistors against aging effects[13,14].HenceNBTI, PBTI …

    2019-3-19 · In fact, aging mechanisms, such as Bias Temperature Instability (BTI), that are present in scaled technologies degrade the conductance of MOS transistors during lifetime (due to an increase in the absolute value of their voltage threshold) [1, 7, 9, 10, 16, 23], thus the delay of the ACDBs also increases overtime.
