  • Publication number: 20240346669
    Abstract: Systems for training a convolutional neural network to register images for masks or wafers in semiconductor manufacturing include a computer processor configured to receive a first pair of images aligned in a first modality and a second pair of images aligned in a second modality. Images in the first pair of images and the second pair of images are a computer aided design (CAD) image pre-aligned with a scanning electron microscope (SEM) image. An affine transformation is generated with a convolutional neural network, using one image from the first pair of images and one image from the second pair of images. The one image from the first pair of images is in the first modality and the one image from the second pair of images is in the second modality. Systems for registering images for masks or wafers in semiconductor manufacturing use the trained convolutional neural network.
