Experimental study of low voltage anode hole injection in thin oxides
In the context of an assessment of the physical mechanisms governing thin oxide degradation, this paper reports an experimental investigation of anode hole injection (AHI) at low gate voltages (VG) and of its correlation to SILC generation. A new technique based on carrier separation measurements is introduced to interpret the behavior of the gate current (IG) during constant VG stress experiments. Our results indicate that AHI is still operative at lower |VG| than previously thought.
