A mathematical model of fully-depleted ultrathin silicon on insulator with buried oxide and four individual gates field effect transistor (G4-FDSOI-FET) has been developed to determine the effects of the oxide thickness as well as the channel width on the threshold voltage. Two dimensional Poisson’s equation has been carried out to model the device. The results show that the threshold voltage depends on the back surface conditions and is a function of structural parameters of oxide thicknesses of front and back gates as well as the width and thickness of the channel.
