摘要

本文推出了具有场限环的平面n

-p结的电场与电位分布的简单理论公式。此理论系根据泊松方程的圆柱对称解结合场限环的边界条件得来

其中假设了场限环在其周围形成的多子势垒小于1电子伏而可略去。文中还给出了场限环的理论设计公式。理论与实验或数字分析结果符合的程度对实用来说是满意的。

Abstract

In this paper

a simple theoretical formula for the distribution of electrical field and electrical potential of the planar n+ - p junction with floating field limiting ring-s（FFLR） is presented. This equation is deduced from the cylindrical symmetry solution of Poisson’s equation in combination with the boundary condition of the field limiting ring

with the assumption that the barrier of majority carriers formed around the rings is lower than leV and can be neglected. The theoretical design formula of the FFLR is also given. The conformity of theory with the result of experimental or mathematical analysis is satisfactory for practice.
