Abstract :
The pseudo-MOS/SOI transistor can be a test device or an inherent part of an SOI device controlled by the back gate. Previous models relied on the depletion approximation to compute the potential and electric field distributions. The advantage is computational simplicity; but it can only be applied just for the depletion regime. The exact solutions of the Poisson equations describe the electric field and potential in the pseudo-MOS transistors for all working regimes. The analytical models are compared with ATLAS simulations.
