Geometric pattern matching technology
enhanced
Geometric pattern matching technology features enhancements for pattern location and alignment that reduce equipment and integration costs, as well as manual operator intervention.
Cognex, the world's leading supplier of machine vision systems, announced at Semicon West that it has extended the capability of its industry-leading PatMax geometric pattern matching technology with new enhancements for pattern location and alignment These new enhancements reduce equipment and integration costs, as well as manual operator intervention, increasing throughput in challenging semiconductor and electronic manufacturing applications

Cognex says that Wieland-Werke AG, one of the world's largest copper strip manufacturers, has integrated Cognex's SmartView ICN web inspection system on its copper pickling line in Germany.
The following PatMax enhancements are now available on Cognex PC-based programmable vision systems: * PatMax XLC (eXtremely Low Contrast)-PatMax XLC improves the ability of PatMax to find barely visible objects or patterns in grainy or faint images, like those produced by powerful magnification techniques such as Scanning Electron Microscopes (SEMs).
PatMax XLC improves wafer alignment for metrology tools, and minimises the need for expensive lighting and optics upgrades in order to analyse noisy, low-contrast images.
* PatMax SA (Scene Alignment)-PatMax provides partial-match alignment that eliminates the need for the entire pattern to be present in an image in order to obtain accurate results.
By enabling portions of the trained model to be outside the field of view, PatMax reduces manual operator intervention, increasing throughput in applications such as defect review stations.
"PatMax has become the most widely used software for semiconductor wafer alignment throughout the world, and we continue to invest in this technology which is so important to our customers," said Jim Hoffmaster, Chief Operating Officer for Cognex. Request a free brochure from Cognex UK ...
"These new enhancements, and other recent developments, such as PatInspect, Synthetic PatMax, and PatFlex, address our customers' most challenging alignment and inspection needs.".
