半导体器件模型参数局部优化提取策略的实现方法

Method of local optimization strategy of semiconductor device model parameters

针对半导体器件模型参数局部优化的提取策略及其实现方法，提出了采用语言描述策略的观点，设计了具体的策略描述语言。用户可通过策略描述语言确定局部优化时参数提取的步骤和流程。这种语言与具体的物理模型无关，与不同的参数提取软件的数据输入格式无关，仅与模型在参数提取软件中的外部接口有关。因而可适用于各种半导体器件模型参数提取软件。这种方式因其参数提取策略和测量数据分离存储，相对于传统的参数提取策略和测量数据绑定存储，有更好的可重用性并更易于维护。

After our research on local optimization strategy of semiconductor device parameter extraction, we propose to use a language to describe optimization strategies and design a specific strategy description larguage. The language can help the end users describe the steps and process of their local optimization strategies. The language is independent of specific physical models and input formats of different parameter extraction software, and is only relevant to the external interface of the software. This language also results in separate storage of extraction strategy and test data, which introduces more reusability and eases the administration of strategies in comparison with traditional binding storage of strategy and data.
