Wafer Sleuth Benefits Capture information on every wafer at every step Wafer tracking examines all wafers across all steps of the fabrication process. Automated analysis of such comprehensive information exposes elusive sources of problems. Wafer Sleuth correlates wafer process position and sequence...

Wafer-level Tracking Versus Other Techniques During its fabrication, a semiconductor wafer passes through hundreds of process steps, pieces of equipment and physical locations. The continuous challenge of any semiconductor manufacturer is to minimize the introduction of defects and reduce sources of...

Wafer Sleuth First conceived over 20 years ago, wafer-level tracking had to overcome technical and organizational barriers before becoming reality. Sleuthworks founders, Gary Scher and James Sorensen, developed the technique at Hewlett-Packard during the 1980s and incorporated the company, Sleuthwo...

Introducing Wafer Sleuth Wafer Sleuth significantly accelerates the discovery of yield loss mechanisms and sources of process variation in semiconductor fabrication by resolving process history from lot level to individual wafer level. ...
