摘要
研究了采用NO快速热氮化SiO2膜的方法制备超薄栅介质膜,并初步制备出约5nm超薄栅的MOS电容和约6nm超薄栅的NMOSFET,NO氮化改善了超薄SiO2膜的性能。
In this paper,ultra thin gate dielectric films fabricated by the method of Nitric Oxide(NO)raped thermal nitridation have been studied.The MOS capacitors with ̄5nm gate dielectrics and NMOSFETs with ̄6nm gate dielectrics have been elementally made.The characteristics of ultra thin SiO 2 films have been improved by NO rapid thermal nitridation.
