Patent ID: 7454312

Claim:
A computer-implemented method for monitoring production of a plurality of semiconductor products to detect potential defect excursions, comprising: (a) collecting equipment based data reflecting equipment performance for a plurality of semiconductor manufacturing tools used for processing the plurality of semiconductor products; (b) collecting product level data reflecting product quality for said plurality of semiconductor products processed on said plurality of manufacturing tools; (c) determining a correlation of at least a portion of said product level data and at least a portion of said equipment based data, wherein determining the correlation includes: receiving an indication of at least one semiconductor product of interest; receiving an indication of a selected time period; locating, in the equipment based data, at least one of the plurality of manufacturing tools on which said at least one semiconductor product of interest was processed; and locating, in the product level data, at least one of the product level data corresponding to the at least one semiconductor product of interest, the at least one located manufacturing tool, and including or proximate to the selected time period; and (d) providing at least one report of said correlation of data.
