3D KMC reliability simulation of nano-scaled HKMG nMOSFETs with multiple traps coupling

This paper presents coupling characteristics of multiple traps in HKMG nMOSFETs by a 3D kinetic Monte-Carlo (KMC) simulator we developed, which includes several fully-coupled multi-physical models: trap generation/recombination, trapping/detrapping to/from channel, metal gate, and the interaction of traps. It shows that activation energy and trapping/detrapping from/to channel/gate impact on coupling of multiple traps. Interaction of traps complicates mechanism in TAT current, BTI, and RTN.
