Abstract
A storage device for storing electron charges includes a substrate, a tunnel oxide layer formed on the substrate, a silicon-rich nitride layer comprising silicon nitride on the tunnel oxide layer, and a modulated interface layer on the silicon-rich nitride layer, wherein the modulated interface layer comprises oxynitride silicide. The electron traps in the modulated interface layer have deeper trap depths than in the silicon-rich nitride layer.
