Abstract
Theoretical calculations indicate that the tunneling currents in silicon nitride or oxynitride are greatly reduced compared to those in SiO/sub 2/ for equivalent oxide thicknesses (EOT) below 4 nm. Experimental results obtained on Jet Vapor Deposited (JVD) nitrides/oxynitrides are shown to verify the theoretical trend. These results suggest that extending the scaling limit well below 4 nm of EOT is possible with the JVD nitride.
