Stress-induced low-level leakage mechanism in ultrathin silicon dioxide films caused by neutral oxide trap generation

摘要

Stress-induced low-level leakage current in ultrathin silicon dioxide films is correlated with neutral oxide trap generation based on first-order kinetics. The conduction mechanism is explained by Fowler-Nordheim tunneling from the leakage spot, generated at the cathode interface, to the neutral oxide trap level, lower in energy than the SiO/sub 2/ barrier height.
