Abstract :
An experimental procedure for the determination of the energy distribution of oxide neutral traps is presented, showing the evolution of the stress-induced damage as a function of Fowler-Nordheim stress fluence and field. It is shown that the traps are mainly distributed around 2 eV from the oxide conduction band. Results are presented for different oxide technologies, investigating the effect of oxide nitridation and growth conditions on the trap energy distribution.
