Physics of Current Filamentation in ggNMOS Revisited: Was Our Understanding Scientifically Complete?

Serious flaws in conventional understanding related to current filamentation and failure in ggNMOS is addressed. The conventional theory is revisited with new physical insights toward current filamentation. Filament dynamics under electrical and thermal instabilities is discussed while correlating it with stress time and current, silicide blocking and S/D doping.
