摘要
介绍了一种纳米MOSFET(场效应管)栅电流和电容的统一模型,该模型基于Schr d inger-Poisson方程自洽全量子数值解,特别适用于高k栅介质和多层高k栅介质纳米MOSFET。运用该方法计算了各种结构和材料高k介质的MOSFET栅极电流,并进行了分析比较。模拟得出栅极电流和电容与实验结果符合。
A unified approach, particularly suitable for evaluation of high-k stack structures consisting of multiple layers of different dielectrics is presented. This approach is based on fully self-consistent solutions to the Schroe dinger-Poisson equations. Various structures and materials of high-k stacks of interest have been examined and compared to access the reduction of gate current in these structures. The results of gate current and capacitance obtained from our model are in very good agreement with experimental data.
