A surface potential based compact model for lightly doped FD SOI MOSFETs with ultra-thin body

In this paper, a new surface potential based compact model for long channel fully depleted SOI MOSFET with lightly doped ultra-thin body is presented. The 1-D Poisson equation is solved using the appropriate boundary conditions, and a closed-form surface potential solution is proposed for the front and back surface potentials. Finally the model was compared to numerical simulations and a good agreement is observed.
