摘要
This paper investigates the hot electron (HE) reliability of ultra thin gate oxide nMOSFETs by means of Full Band Monte Carlo (FBMC) simulation. First, a qualitative explanation of the smaller hot electron induced degradation (HEID) for thinner oxides observed in [1] is presented. Then, HEID in two different types of nMOSFET suitable for sub-0.1 mu m applications is analyzed as the devices are properly scaled below O.1 mu m, addressing the question whether gate oxide thickness can be scaled down to 1nm from the hot electron degradation point of view. Finally, the validity of usual extrapolation techniques of HEID lifetime from experimental data usually available in the range 2.5V less than or equal to V-DD less than or equal to 5V to low voltages is addressed.
