  • Publication number: 20230288822
    Abstract: Actual physical locations of dies on a substrate package may be identified without using a full metrology scan of the substrate. Instead, one or more cameras may be used to efficiently locate the approximate location of any of the alignment features based on their expected positioning in the design file for the packages are substrate. The cameras may then be moved to locations where alignment features should be, and images may be captured to determine the actual location of the alignment feature. These actual locations of the alignment features may then be used to identify coordinates for the dies, as well as rotations and/or varying heights of the dies on the packages. A difference between the expected location from the design file and the actual physical location may be used to adjust instructions for the digital lithography system to compensate for the misalignment of the dies.
