This paper presents an analytical breakdown model including self-heating ef
fect (SHE) for NMOSFEF devices. Model evaluation is taken for a wide ambien
t temperature range, from room temperature to 200 degrees C, It is found th
at the device self-heating effect is suppressed when ambient temperature is
increased, in addition, our results suggest that the conventional MOSFET b
reakdown model without considering the self-heating effect call overestimat
e the breakdown characteristics for the short-channel devices. (C) 2000 Els
