Abstract
This paper provides an improved surface potential equation for compact modeling of dynamically depleted silicon-on-insulator MOS device. It removes the non-physical front-gate capacitance prediction and the discontinuity at the flat-band condition present in previous works. It also includes for the first time the back gate effect observed at negative back gate voltage when the silicon film is partially depleted. It relies on, firstly, an approximated description of the front-depletion/back-accumulation mode of operation that has always been ignored by now, and secondly, an appropriate mathematical conditioning. The model is validated by 3D TCAD simulations.
本文为动态耗尽型硅绝缘体 MOS 器件的紧凑建模提供了一种改进的表面电势方程。它消除了之前工作中存在的非物理前栅极电容预测和平带条件下的不连续性。它还首次包含了硅薄膜部分耗尽时在负后栅电压下观察到的后栅效应。首先，它依赖于对迄今为止一直被忽视的前耗尽/后累积工作模式的近似描述；其次，它依赖于适当的数学条件。三维 TCAD 仿真验证了该模型。
