High-k gate dielectric
WebAbstract: A new method, called gate current Random Telegraph Noise (I G RTN), was developed to analyze the oxide quality and reliability of high-k gate dielectric MOSFETs. First, a single electron trapping/detrapping from process induced trap in nMOSFET was observed and the associated physical mechanism was proposed. Web1 de mai. de 2008 · 1.. IntroductionIncreased gate leakage is one major limiting factor on aggressive scaling of gate dielectric for deep-submicron CMOS technology [1].Search has been on for a suitable high-permittivity (high-k) gate dielectric, which can replace SiO 2 [2].However, this gives rise to significant fringing-capacitance, consisting of gate …
