Gate oxynitride was grown in NO for the first time. This approach can
provide a tight N accumulation near the Si/SiO2 interface. Much lower
thermal budget is required for an NO process than for an N2O process t
o produce an oxynitride with useful properties. Submicron MOSFET's wit
h NO oxynitride showed superior current drive characteristics and comp
arable hot carrier immunity to those with N2O oxynitride.
