摘要

The electrical characteristics of thin gate dielectrics prepared by low temperature (850 °C) two-step N₂O nitridation (LTN) process are presented. The gate oxides were grown by wet oxidation at 800 °C and then annealed in N₂O at 850 °C. The oxide with N₂O anneal, even for low temperature (850 °C), had nitrogen incorporation at oxide/silicon interface. The charge trapping phenomena and interface-state generation (ΔD_itm) induced by constant current stressing were reduced and charge-to-breakdown (Q_bd) under constant current stressing was increased. This LTN oxynitride was used as gate dielectric for N-channel MOSFET, whose hot-carrier immunity was shown improved and reverse short channel effect (RSCE) was suppressed.
