The parasitic bipolar transistor inherent to grounded gate nMOSts is m
odelled accounting for the specific conditions applied by CDM ESD stre
ss. The impact of the gate length on the CDM-specific bipolar saturati
on mode is addressed. The different operation modes occurring during C
DM ESD stress translate to self-heating which explains the observed te
st results. Copyright (C) 1996 Elsevier Science Ltd
