水平巷道-
The macro model of drift region resistance was established based on the solution of poisson ’ s equations and continuity equations. by the combination of spice mos ( level = 3 ) and the macro model, the complete dddmos model was then obtained, which accords well with simulated data. by simulating and comparing different devices of different process parameters, the model is applicable for different bias regions and can be useful in the power integrated circuit research in future
首先介紹了器件建模的基本原理及相關模擬技術，然後利用工藝模擬軟體生成器件基本結構，並對其基本特性進行了分析;分析了業內和學術界比較通用的高壓器件建模的方法，隨后在模擬實驗的基礎上著重分析了dddmos的物理特性，在求解泊松方程、連續性方程等基本方程的基礎上，建立有物理意義的漂移區電阻的宏模型;隨后結合spicemos （ level = 3 ）模型而得到完整的dddmos模型，此模型與模擬數據符合得比較好，通過對不同工藝參數的器件進行模擬比較，該模型能夠覆蓋不同的工作偏壓范圍，具有較明確的物理意義，對今後的功率集成電路的研發有一定的參考意義。 -
