Abstract: 成功制备了EOT(equivalent oxide thickness)为2.1nm的Si3N4/SiO2(N/O) stack栅介质,并对其性质进行了研究.结果表明,同样EOT的Si3N4/SiO2 stack栅介质和纯SiO2栅介质比较,前者在栅隧穿漏电流、抗SILC性能、栅介质寿命等方面都远优于后者.在此基础上,采用Si3N4/SiO2 stack栅介质制备出性能优良的栅长为0.12μm的CMOS器件,器件很好地抑制了短沟道效应.在Vds=Vgs=±1.5V下,nMOSFET和pMOSFET对应的饱和电流Ion分别为584.3μA/μm和-281.3μA/μm,对应Ioff分别是8.3nA/μm和-1.3nA/μm.
