Resumo

This paper aims at analyzing the electrical characteristics of 2-level Stacked Nanowire MOSFETs at low temperatures. Fundamental device parameters such as threshold voltage, subthreshold slope and transconductance are evaluated in the temperature range of 160K to 400K. The influence of fin width variation is also studied. An analytical model of multiple-gate nanowire MOSFETs is employed to explain the experimentally observed data. It is demonstrated that the threshold voltage increases linearly with the temperature reduction. Stacked nanowires with wider fin width presents larger threshold variation with temperature. (AU)
