Abstract
Official abstract text for this publication.
A silicon-oxide-nitride-oxide-silicon (SONOS) device is disclosed. The SONOS device includes a substrate; a first oxide layer on the substrate; a silicon-rich trapping layer on the first oxide layer; a nitrogen-containing layer on the silicon-rich trapping layer; a silicon-rich oxide layer on the nitrogen-containing layer; and a polysilicon layer on the silicon-rich oxide layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A silicon-oxide-nitride-oxide-silicon (SONOS) device, comprising: a substrate; a first oxide layer on the substrate; a silicon-rich trapping layer on the first oxide layer, wherein the silicon-rich trapping layer comprises a silicon nitride (SiN) layer and a silicon-rich SiN layer; a nitrogen-containing layer on the silicon-rich trapping layer; a silicon-rich oxide layer on the nitrogen-containing layer; and a polysilicon layer on the silicon-rich…
