Process for treating ONO dielectric film of a floating gate memory cell

Process for treating ONO dielectric film of a floating gate memory cell

A process to deposit a silicon dioxide layer on a silicon nitride layer for an ONO stack of a floating gate transistor. Silicon dioxide is deposited on a silicon nitride layer and annealed in a batch furnace or a single wafer rapid thermal anneal tool in a nitrogen oxide (NO) or nitrous oxide (N2O)...

Zusammenfassung:A process to deposit a silicon dioxide layer on a silicon nitride layer for an ONO stack of a floating gate transistor. Silicon dioxide is deposited on a silicon nitride layer and annealed in a batch furnace or a single wafer rapid thermal anneal tool in a nitrogen oxide (NO) or nitrous oxide (N2O) ambient environment.
