Cross-Correlation
A statistical measure timing the movements and proximity of alignment between two different information sets of a series of information.

These include data mining algorithms to automatically identify causes of difficult classes of yield issues, spatial signature analysis software to detect spatial patterns on wafers and correlate these signatures to the process equipment and operating conditions that may have caused them, and the complete integration and cross-correlation of defect and process data.
