在本篇論文中，我們開發出新型重心版模組，能以任意三角形網格當基本元素，模擬二維的半導體元件，相對於以往需要避開或忽略鈍角三角形的產生，新版模組增加網格設定的彈性空間，並且有效減少模擬需要的節點數；首先我們利用簡易電阻驗證其理論電阻值，並且模擬PN二極體的特性曲線作驗證，接著將新版模組應用至圓柱形元件，開發出新形的梯形網格分割方式，探討其模擬精確值，最後分析當新版模組遇到大角度鈍角三角形網格時的模擬問題。;In this thesis, we have successfully developed a new type module which is composed of any triangle mesh elements to simulate 2D semiconductor device. The new type module increases the flexibility to set up the mesh, and it can also effectively decreases the total amount of computation nodes. At first, a simple 2D resistor and PN diode will be simulated and compared to the theoretical for verification. Then, the new module will be applied to simulate the cylindrical semiconductor element by the new version of the trapezoidal mesh segmentation mode, and the simulation result will be compared to the exact value. Finally, we will discuss the problem when the new type module is used to simulate the large angle obtuse triangle mesh.
