Latest Patents

Moghadam's recent patents showcase his expertise in complex detection systems. One of his latest inventions, "Detecting and Classifying Surface Defects with Multiple Radiation Collectors," involves a sophisticated system designed to detect and classify defects on a substrate's surface. This system utilizes multiple radiation collectors, with a first targeting assembly directing radiation onto the substrate. The first collecting assembly captures specularly reflected radiation to produce signals, while subsequent assemblies gather scattered radiation caused by defects and micro-roughness. A processor analyzes these signals, enabling precise detection and classification of defects.

Another noteworthy patent, "Substrate Edge Inspection," features an apparatus for inspecting substrate edges. This invention employs a light source to create a semi-annular scanning beam that directs onto the edge of the substrate. A parabolic surface then directs the specularly reflected light to a detector, which generates signals for defect analysis. This innovative approach significantly improves edge inspection processes.
