W8614EP Model Builder Program(MBP)可靠性模块 MOSRA – TMI 包括用于 MOS 可靠性分析(MOSRA)和 TSMC 模型接口(TMI)老化模型的提取套件。
MBP 可靠性模块为 HSPICE 的内置 MOSRA 模型提供了一个提取环境,该模型可以仿真老化效应,包括热载流子注入(HCI)和偏置温度不稳定性(BTI)。因此,用户可以评测器件在实际工作条件下性能逐渐下降的特性。
内置 MOSRA 模型包括两个等级:1 级和 3 级。这两个等级之间的区别请参见下表。
MBP 2019 版本中新增了 MOSRA 3 级模型的提取套件。基于脚本的流程能够完全自动运行并且可以定制,如下图所示:

此处是拟合结果的屏幕快照:

除了 MOSRA 之外,MBP 可靠性模块还支持 TMI 老化模型生成。TMI 是采用 C 语言开发的建模 API,支持标准紧凑模型的扩展。用户可以测量器件性能逐渐下降的特性,并评测 40 nm 及以下工艺的应力效应。
