An Analysis of GAT′s Optimal Designing

Abstract

【中文摘要】 通过作者最近建立的关于电力半导体器件 GAT的集电结耗尽层电位分布和电场分布的二维解析模型即《GAT栅屏蔽效应二维解析模型》、《GAT实现高频率与高基区穿通电压兼容特性分析》以及《GAT实现高电流增益与高雪崩击穿电压兼容特性分析》,定量研究了优化设计 GAT的材料参数和结构参数的关系。 【英文摘要】 By the aid of the two dimensional analytical model of the electric potential and field distribution in power semiconductor device GAT′s collector depletion space in the cutoff state,i.e.the two dimensional analytical model to GAT′s gate shielding effect,and the analysis to GAT′s compatibility between high frequency and high base region punchthrough voltage and the analysis to GAT′s compatibility between high current gain and high avalanche brea..
