Title: Method and system for classifying defects in wafer using wafer-defect images, based on deep learning
IPC: G06N20/00
Filed: 2020-09-16
Abstract: The present invention provides a method and a system (100) for classifying a defect of a wafer by using a wafer defect image based on a deep learning network. One embodiment of the present invention uses a synergy effect between various modalities of the wafer defect image for classification determination. Also, a mixture of modalities is added to acquire information from different sources such as a color image, ICI, and a black and white image to classify the defect image. In addition to the mixture of modalities, a reference image can be used for each modality. The reference image of each imaging modality can be provided for a deep learning model to concentrate on the defect instead of the related basic lithography of the defect image. Also, the reference image can be provided for a training process of the deep learning model to greatly reduce the number of labeled images and training epochs required for convergence of the deep learning model.
