摘要
分析了4H-SiC射频功率MESFET栅源和栅漏区域内的表面态形成,建立了包含表面态影响的非线性解析模型,理论描述了对器件输出特性的稳态、瞬态响应.本模型具有计算简单、物理概念清晰的特点.
An analytical non\|linear model including surface\|state effect is proposed for 4H\|SiC power MESFET's with which the impact of suface damage at the ungate recess region caused by the dry\|etching process on the output steady\|state characterization can be illustrated clearly.The model has the advantage in very simple calculations over the 2D numerical simulations, therefore suitable for process analysis of SiC power MESFET's.
