摘要：
We have proposed a subthreshold current model for fully depleted short channel double-gate (DG) MOSFETs by considering the structure asymmetry. Potential distribution is derived by solving 2-D Poisson's equation using variable separation technique. The degraded subthreshold characteristics variations due to structure asymmetry such as the difference of oxide thicknesses or biases between front-gate and back-gate can be exactly described. Also, body doping and other deep nanoscale design parameters such as body thickness and channel length were considered. The models have been verified by comparing with device simulations' results and found very good agreement. Copyright (C) 2013 John Wiley & Sons, Ltd.
