Latest Patents

Yen-Hsun Chen holds a patent for a "Method and system for rapid inspection of photolithography reticle." This method involves training an analysis model of the reticle inspection system using a machine learning process. It generates a difference threshold based on this process, stores a reference image, and creates a scan image of a reticle. The method compares the scan image to the reference image to generate a relative difference value. If this value is less than the difference threshold, the reticle is determined to be non-defective. Conversely, if the value exceeds the threshold, the reticle is deemed defective. This innovative approach streamlines the inspection process, ensuring higher quality in photolithography applications.
