  • 基于应变Si/SiGe器件结构,本文建立了统一的应变Si NMOSFET电荷模型. 该模型采用电荷作为状态变量,解决了电荷守恒问题. 同时采用平滑函数,实现了应变Si NMOSFET端口电荷及其电容,从亚阈值区到强反型区以及从线性区到饱和区的平滑性,解决了模型的连续性问题. 然后采用模拟硬件描述语言Verilog-A建立了电容模型. 通过将模型的仿真结果和实验结果对比分析,验证了所建模型的有效性. 该模型可为应变Si集成电路分析、设计提供重要参考.
    Based on the structure of strained Si/SiGe NMOSFET, a unified charge model is presented, in which charge conservation is guaranteed by using the charge as the state variable. The model describes device characteristics from subthreshold to strong inversion as well as from the linear to the saturation operating regions using a smoothing function, and guarantees the continuities of charges and capacitances. Furthermore, capacitance models have been presented using Verilog-A, a language to describe analog behavior. Comparisons between the model and measured data show that the charge model can describe the device characteristics well. The proposed model is useful for the design and simulation of integrated circuits made of strained Si.
