Sentaurus是一款由Silvaco Technologies提供的广泛用于半导体设备建模和模拟的商业软件。对于模拟垂直NPN双极型晶体管(Bipolar Junction Transistor,BJT)的一维掺杂结构, Sentaurus通常涉及TCAD (Technology Computer-Aided Design) 程序,它允许用户设置掺杂浓度、扩散系数等参数。
下面是一个简化的Python脚本风格的示例,用来描述垂直NPN BJT的1D掺杂配置,实际操作会更复杂并需要使用特定的API:
```python
from silvacos.sentaurus_simulator import *
# 创建新的模拟项目
project = Project("Vertical_NPN_BJT")
# 设置材料属性
material = Material()
material.set doping_profile({
"substrate": "P",
"Emitter": "N", # 阴极
"Base": "N", # 基区
"Collector": "P", # 阳极
"Depth_Emitter": 5e-6,
"Depth_Base": 10e-6, # 基区宽度
})
# 添加层到结构
structure = Structure(project)
structure.add_layer(material, name="Substrate")
structure.add_layer(material, name="Emitter", depth=Depth_Emitter)
structure.add_layer(material, name="Base", depth=Depth_Base)
structure.add_layer(material, name="Collector")
# 设置边界条件
boundary_conditions = {
"Substrate": {"type": "FixedPotential", "value": 0},
"Emitter": {"type": "Neumann"},
"Collector": {"type": "FixedPotential", "value": -0.7}, # 标准集电极偏置电压
}
structure.set_boundary_conditions(boundary_conditions)
# 运行模拟
run_simulation(project)
