应变SiGe p型金属氧化物半导体场效应管栅电容特性研究*
Study on gate capacitance-voltage characteristics of strained-SiGe pMOSFET∗
摘要
Abstract
The gate capacitance-voltage (C-V) characteristic of strained SiGe pMOSFET is very different from that of bulk Si pMOSFET, and can be strongly affected by the channel doping. In this paper, we first study the formation mechanism of the“plateau”which can be observed in the gate C-V characteristics of strained SiGe pMOSFET, and then present a physics based analytical model to predict the gate C-V characteristic of strained SiGe pMOSFET. It is found that this plateau is channel doping dependent. The results from the model are compared with the experimental results and they are found to be in excellent agreement with each other, giving the evidence for its validity.关键词
