In this paper, the authors show that for oxides less than /spl sim/3.5 nm, interfacial traps generated from direct tunneling stress result in a sense voltage dependent SILC mechanism that can dominate the gate leakage current at low operating voltages.
Abstract
Stress-induced-leakage-current (SILC) is an important concern in ultrathin gate oxides because it may impose constraints on dielectric thickness scaling. We show that for oxides less than /spl sim/3.5 nm thick, interfacial traps generated from direct tunneling stress result in a sense voltage dependent SILC mechanism that can dominate the gate leakage current at low operating voltages.

Experimental evidence for voltage driven breakdown models in ultrathin gate oxides

TL;DR: In this article, the authors show that hole injection does not completely account for all of the trap generation mechanisms observed during direct tunneling stress and that the anode hole injection model is still operative at low voltages.

Mechanism for stress-induced leakage currents in thin silicon dioxide films

TL;DR: In this paper, it was concluded that the generation of neutral electron traps in thin oxides is the dominant cause of leakage currents introduced in the low-field, direct-tunneling regime of thin oxide during high-field stress.

Observation of positively charged state generation near the Si/SiO2 interface during Fowler–Nordheim tunneling

TL;DR: In this article, a sensitive probe of the oxide interfacial region, capable of locating and detecting as few as 1010 cm−2 positive states was presented, which is consistent with the mechanism of breaking strained Si-O-Si bonds near the interface, observed in x-ray photoelectron spectroscopy experiments.
