Profiling of deep traps in silicon oxide-nitride-oxide structures

Research output: Contribution to journalArticlepeer-review

Abstract

Thermally stimulated exoelectron emission has been applied for high-resolution depth profiling of traps in amorphous SiO2/Si 3N4/SiO2 (ONO) dielectric stacks used in silicon-oxide-nitride-oxide-silicon (SONOS) memory devices. It is shown that maximum density of traps responsible for charge storage in ONO structures is at the interface between top silicon oxide and silicon nitride in ONO.
