Method for registering circuit design and microscope images
The patent US12062196B2 outlines a method and system for registering a circuit design layout with a scanning electron microscope (SEM) image. The process begins by providing both the circuit design layout, which includes at least one design pattern, and the SEM image, which contains corresponding scanning patterns. The method involves several steps, including binarizing both images to create binary representations where design patterns and scanning patterns are distinctly marked. Gaussian filtering is then applied to enhance the central axes of these patterns, followed by an image template matching method to achieve accurate registration of the two images.
Further details of the method include specific steps for obtaining coordinates of the scanning patterns and determining corresponding areas in the circuit design layout. The method also allows for smoothing and filling of design patterns to improve the binary images. Additionally, the system comprises various modules, including input, binary processing, Gaussian filtering, and registration modules, which work together to facilitate the registration process. The patent also describes an electronic device that can execute the method through stored computer programs, highlighting its applicability in advanced circuit design and analysis.
