臺灣博碩士論文加值系統

本篇論文乃是針對非晶矽薄膜電晶體之數值模擬提出一套網路分析模型,
主導半導體行為的伯松及連續方程式將被轉換成為相對應之等效電路,因
此,如電流源,電阻,電感之類的電路元件便可以被用來實現上述的半導體
方程式,對元件特性的研究而言,數值模擬是一項很有效的工具,但是有時
發展這樣的工具並不是那麼容易,網路分析法提供了一個使用電路模擬器
來處理半導體元件數值模擬的一個途徑,也簡化了數值模擬時所可能會遭
遇到的複雜度,在另一方面,此一方法,使得元件與外部電路之間的混型模
擬變得更為容易,而這也是一般元件模擬器所不容易做到的,這篇論文的最
後,將展現包括電流-電壓,電容-電壓及暫態特性在內的模擬結果,而這些
結果都具有相當的合理性並且也令人滿意.

This thesis presents a network model for a-Si TFT two-
dimensionalnumerical simulation. The Poisson and continuity
equations are formulated into equivalent circuits so circuit
elements like current sources, resistors and capacitors can be
used to implementedthe equations. Numerical simulation is a
powerful tool for device research, but sometimes it is hard to
implement. This method not only provides the availability to
simulate semiconductor devices numerically by using a circuit
simulator, but also reduce the complexity of numerical
simulation. In addition, this method makesthe mixed-mode
simulation between a semiconductor device and external circuits
easier. The simulation results which include I-V, C-V
andtransient characteristics are all reasonable and
satisfactory.
