Latest Patents

Wilson holds a patent for a "System for finding the orientation of a wafer." This invention allows for the determination of a semiconductor wafer's orientation without the need for physical handling, utilizing a non-contact method. The system leverages the known positions of the wafer and its orientation features to ascertain the wafer's orientation. A curved band image is created, which includes the orientation feature, and this image is transformed into a straight band image. The longitudinal position of the orientation feature is then identified within the straight band image's coordinate system, which is subsequently converted into an angular displacement in the curved band image's coordinate system, thus providing the wafer's orientation.
