Abstract :
A previous charge-sheet model (A. Ortiz-Conde et al., Solid-State Electron., vol.31, p.1497-1500, Oct. 1988) for the equilibrium inversion layer charge of the thin-film SOI MOSFET is extended to account for nonequilibrium conditions, which occur under normal operation of the device. This is of vital importance to an analytical description of its current-voltage characteristics. The extended model is valid for all inversion conditions and accounts for the charge coupling between the front and back gates. The resulting analytical expression for the inversion-layer charge produces an error of less than 5% with respect to the numerical results obtained from the one-dimensional Poisson equation with the approximation of quasi-equilibrium
