METHOD FOR OBTAINING TRAINING DATA FOR TRAINING A MODEL OF A SEMICONDUCTOR MANUFACTURING PROCESS

摘要

A method for obtaining a training data set including synthetic metrology data, the training data set being configured for training of a model relating to a manufacturing process for manufacturing an integrated circuit. The method includes obtaining behavioral property data describing a behavior of a process parameter resultant from the manufacturing process and/or a related tool or effect. Additionally, or alternatively metrology data performed on a structure formed by the manufacturing process and/or a similar manufacturing process may be obtained. Using the behavioral property data and/or metrology data, synthetic metrology data is determined, which describes the effect of variations in the manufacturing process, and/or a related tool or effect on the process parameter. The model is trained using the training data set including the synthetic metrology data.
