Abstract:	本論文的主旨為利用 C 語言去模擬 1/4 球面網格之半導體元件，一開始利用有限元素法去建立最基本的網格，進而將網格構成的單位元素等效成等效電路模型以便將方程式(如帕松方程式和電子電洞連續方程式)帶入電路模型中進行運算求所需之物理和電路特性。在架構建立完之後，可以透過網路上的動態幾何代數軟體(GeoGebra)去塑造所期望的 1/4 球面網格，先在球座標上架構所需的點數到運用體積比驗證我們的 1/4 球面網格建構是否精準，最後模擬我們想要的元件特性曲線，可得知結果與理論值相差無幾，說明了我們此套開發的程式模擬架構是能應用在 1/4 球面網格半導體元件的模擬。 ;The main purpose of this thesis is to use C language to simulate the semiconductor element of the 1/4 spherical grid. In the beginning, the finite element method is used to establish the most basic grid, and then the unit element grid can transform into an equivalent circuit, which can convert the Equations (such as the Poisson equation and the electron-hole continuity equation) to obtain the required physical and circuit characteristics. After the architecture is established, we can use the dynamic geometric algebra software (GeoGebra) to shape the 1/4 spherical grid. First, we set the nodes in spherical coordinates and then used the volume ratio to verify the accuracy of the 1/4 spherical grid structure. Finally, we can simulate the characteristic curve we want to show that the simulation results are almost the same as the theoretical values, which shows that the program simulation framework we developed can be applied to the simulation of 1/4 spherical grid semiconductor devices.
