摘要: An automated signature detection system and method of use and, more particularly, a predictive modeling component configured to accurately predict maintenance events for optical elements used in lithographic tools. The system comprises at least one module configured to analyze data associated with power illumination at a surface. The at least one module also is configured to fit a curve to the analyzed data using an exponentially based decay model.
