Sentaurus TCAD学习——SDE

一. 知识点

1. 器件坐标系

SDE有不同的坐标系，还要注意区别2D和3D情况：

UCS(Unified Coordinate System)；DF–ISE coordinate system;

2. 区域交叠布尔运算

SDE根据用户脚本的布尔运算值处理器件几何结构交叠区域：

Syntax
(sdegeo:set-default-boolean boolean-value)

 3. 单位

长度：

Sentaurus Structure Editor itself makes no assumptions about the unit of length used to define
a geometric object. Other TCAD Sentaurus tools, such as Sentaurus Device, however, will
assume that the unit of length is 1 μm . In this indirect sense, the effective default unit of length
in Sentaurus Structure Editor is 1 μm.

4. 不用内置随机数函数写一个生成随机数的函数

线性同余法；Box - Muller 方法；
