摘要: 提出了一种无须进行电离积分的用于高压结终端模拟的边界元素法,分析了界面电荷对FP-JTE终端结构击穿电压的影响,结果表明击穿电压几乎与界面电荷浓度呈线性关系,场板可减弱界面电荷对击穿电压的影响。

Abstract: A 2-D boundary element method is introduced for the simulation of high-voltage Junction termination.With the concept of critical electric field,this method does not need to perform ionization integral.The effect of interface charge to the breakdown voltage of FP-JTE junction termination has been analyzed.The result shows that the breakdown voltage almost linearly depends on the density of interface charge,and the field plate can suppress the breakdown voltage sensitivity to interface charge.

Key words: Boundary Element Method, field plate, planar junction termination, junction termination extension
