摘要
本文对源漏n+浅结注入的自对准GaAsMESFET内部的电位、电场及载流子浓度的稳态分布进行了二维数值分析,分析表明,不同n+注入深度对器件的特性有一定的影响,当n+注入深度为有源层厚度的1/4时,畴的体积最小.适当选取n+区边缘与栅之间的距离可提高器件的击穿电压.
This paper presents a two-dimensional numerical analysis method and program for self-aligned GaAs MESFET.by using finite-differential method. For different n ̄+depth, the distributions of potential, electric field and carrier concentration along the channel and the current-voltage characteristic curve are studied. The results show that the deeper the n ̄+ implanted depth, the bigger will the domain be. Reasonable Lgs and Lgd will improve the device breakdown voltage.
