Publication number: 20190198405Abstract: Detecting mismatches among a plurality of manufacturing tools of the same type and operating on a first semiconductor wafer. A server receives metrological data and time series data applicable to the first semiconductor wafer from each of the plurality of manufacturing tools. The server applies a plurality of statistical tests to the metrological data and a data mining technique to the time series data. The server assigns a score to each result from applying the plurality of statistical test and the data mining technique to the plurality of manufacturing tools, the scores indicating a degree of mismatch among the plurality of manufacturing tools. Responsive to the sum of scores exceeding a predetermined threshold, the server declares a mismatch condition for each tool among the plurality of manufacturing tools.Type: ApplicationFiled: December 22, 2017Publication date: June 27, 2019Inventors: Zhiguo LI, Robert J.
