Abstract
A new method to estimate the channel doping concentration (Nd) in highly doped fully-depleted SOI MOSFETs is proposed with simulation results based on the electron charge in partially depleted regime derived from Gauss's law. The separation between the threshold voltage (Vth) and the flat band voltage (Vfb) extracted from simulation results linearly increases as a function of Nd (Nd = 1×1018/cm3) and the range of Nd for proposed method varied with Si thickness because it depends on the maximum depletion width at given Nd. The nanowire channel has wider range of Nd, compared to the planar channel, due to the reinforced gate control by sidewall gates.
