Abstract

In this work, the temperature dependence of electrical parameters of nanoscale SOI (silicon-on-insulator) TG (triple gate) n-FinFET (n-channel Fin field effect transistor) was investigated. Numerical device simulator <TEX>$ATLAS^{TM}$</TEX> was used to construct, examine, and simulate the structure in three dimensions with different models. The drain current, transconductance, threshold voltage, subthreshold swing, leakage current, drain induced barrier lowering, and on/off current ratio were studied in various biasing configurations. The temperature dependence of the main electrical parameters of a SOI TG n-FinFET was analyzed and discussed. Increased temperature led to degraded performance of some basic parameters such as subthreshold swing, transconductance, on-current, and leakage current. These results might be useful for further development of devises to strongly down-scale the manufacturing process.
