In this work, the epitaxial graphene channel formed on 3C-SiC grown on a Si substrate backgate transistor was designed, fabricated and characterized for electronic and optoelectronic applications. Even though a significant amount of the gate leakage current is observed, the experimental results show the device works as an n-type transistor as well as an infrared photovoltaic transistor with the backgate...
HfSiON is one of the most promising alternative gate dielectric materials for low standby power (LSTP) application. Recently, DC performance, gate leakage current, and reliability have been reported. However, study of analog performances of CMOS with HfSiON gate dielectrics is not sufficient. In this paper, the authors discuss 1/f noise and matching of CMOS with HfSiON gate dielectrics and predict...
We found a new anomalous gate leakage current (AGLC) of ultra-thin gate-SiON, which may directly impact standby leakage and yield for 65 nm node and beyond. We have identified the AGLC mechanism and also developed gate-stack fabrication process as effective countermeasures. Reducing gate-SiON to less than 1.3 nm induces AGLC leading to reliability degradation in nFET. With relatively large Phosphorous...
