Abstract:
Systems and methods for tool health monitoring and matching through integrated real-time data collection, event prioritization, and automated determination of matched states through image analysis are disclosed. Data from the semiconductor production tools can be received in real-time. A control limit impact (CLI) of the parametric data and the defect attributes data can be determined and causation factors can be prioritized. Image analysis techniques can compare images and can be used to judge tool matching, such as by identifying one of the states at which the two or more of the semiconductor manufacturing tools match.
