摘要: 介绍自行研制的通用二维半导体器件模拟软件GSS,该软件的求解器同时实现了漂移扩散模型和流体动力学模型,可对多种材料、不同结构的器件进行稳态和瞬态计算.作为算例,应用该软件对NPN三极管和MESFET管进行了数值模拟,给出了IV曲线、电子密度分布和温度变化等.

关键词: TCAD, 半导体数值模拟, 流体力学模型, 漂移扩散模型

Abstract: We develop a general-purpose two-dimensional semiconductor simulator (GSS),by which the drift-diffusion model and hydrodynamic model are calculated.It calculates steady-state and transient responses of the devices with different materials structures and is applied to an NPN transistor and MESFET.IV curves,electron density distribution and temperature variation are obtained.

Key words: TCAD, semiconductor device simulation, hydrodynamic model, drift-diffusion model
