Abstract :
In this paper, an analytical model of subthreshold swing for the double-gate accumulation-mode P-channel SOI MOSFET is described. The model is based on Possion´s equation and depletion approximation, and the relation of the subthreshold swing with both the gate oxide capacitance and the interface trap density is obtained. The model is verified by experiment and by numerical simulation. Also an approach to extracting the interface trap density with subthreshold swing is proposed.
