Abstract

Considering effects of nonuniform doping profile in vertical and lateral directions of MOSFET and solving a quasi two-dimensional differential equation for the surface potential, we have proposed a new threshold voltage model. Our model predicts well an initial roll-up of the threshold voltage with decreasing channel lengths and reduction of it due to the reverse short-channel effects and the short-channel effects.

深亚微米MOSFET的可扩展阈值电压模型
考虑到MOSFET在垂直方向和横向方向上掺杂分布不均匀的影响,并求解表面电位的准二维微分方程,提出了一种新的阈值电压模型。我们的模型很好地预测了初始阈值电压随着通道长度的减少而上升,并且由于反向短通道效应和短通道效应而降低。
