This paper presents a simulation framework for reliability analysis of PMOS devices in the TCAD Sentaurus environment. The degradation of parameter is based on the numerical solution for the two-stage NBTI model mechanism. We demonstrate and analyze the voltage degradation, Vth of a high-k HfO2 dielectric pMOSFET structure with effective oxide thickness (EOT) of 1.092 nm. After 1000s of stress, the...
Lifetime of pMOSFETs is limited by negative bias temperature instability (NBTI). NBTI causes the degradation of drive current and threshold voltage of p-MOSFETs. This paper presents the comparison of DC and pulse train analysis on sub micrometer pMOSFETs lifetime prediction using on-the-fly (OTF) method. The SiO2 conventional PMOS transistor having effective oxide thickness (EOT) between 1.8nm and...
