【摘要】 介绍用数值分析方法对6000V特大功率晶闸管的正向压降进行计算机模拟,对降低正向压降的途径进行计算机辅助分析的一些基本考虑和主要结果。在强调重掺杂与大注入效应的时候,提出了一种修正的少数载流子寿命模型。根据模拟结果对决定正向压降的物理因素和工艺因素进行了讨论。更多还原

【Abstract】 Some basic considerations on simulation of the forward voltage drop in 6000 V thyristorsare presented.A corrected model for lifetimes of minority carriers in different parts ofthyristor is suggested in response to heavy doping and high injection. The physical mechanismand processing factors to be responsible for forward voltage drop are discussed based on thesimulation results.更多还原
