  • Patent number: 10488347
    Abstract: A defect classification method in accordance with the present invention uses two types of images output from the defect inspection device 150 (i.e., the first inspection image generated from a luminance signal sequentially output from a detector SE and the second inspection image generated from a difference of the signals from an adjacent portion in a region where the defect exists). The first inspection image includes information for discriminating unevenness of the defective shape. Also, while it is difficult to discriminate unevenness of the defective shape by the second inspection image, the second inspection image includes information on a luminance distribution emphasizing a defective section. The region of the defective section is extracted from the second inspection image to be applied to the first inspection image and thereby define an arithmetic processing area, and the image processing is performed within the arithmetic processing area to compute a feature amount.

  • Patent number: 9685906
    Abstract: Methods for fast and accurate mapping of passivation defects in a silicon wafer involve capturing of photoluminescence (PL) images while the wafer is moving, for instance, when the wafer is transported on a belt in a fabrication line. The methods can be applied to in-line diagnostics of silicon wafers in solar cell fabrication. Example embodiments include a procedure for obtaining the whole wafer images of passivation defects from a single image (map) of photoluminescence intensity, and can provide rapid feedback for process control.

  • Patent number: 9665803
    Abstract: A dictionary for detection of an object is created from an image obtained by performing an image process, which depends on a first image process parameter, on the training image of the detection target object. The dictionary created based on the image process depending on the first image process parameter is determined, based on a result of detecting the object from an image obtained by performing an image process, which depends on the first image process parameter, on a photographed image based on the dictionary. A second image process parameter is determined, based on a result of detecting the object from an image obtained by performing an image process, which depends on the second image process parameter, on the photographed image using the determined dictionary.

  • Patent number: 9626755
    Abstract: In a mask inspection apparatus, an optical image acquisition unit acquires an optical image of a pattern in a mask by irradiating light. A reference image generation unit generates a corresponding reference image. A defect detection unit detects a defect of the pattern by comparing the two images. A misplacement data processing unit obtains a misplacement amount of the pattern from the images, and generates misplacement data. A misplacement map processing unit generates and outputs the map to the defect detection unit. The defect detection unit includes, a first comparison unit for comparing the images, a threshold value reconfiguring unit for specifying a portion of the map corresponding to the defect detected, reconfiguring a threshold value according to the shape of the defect and the misplacement direction of the optical image of the specified portion, and a second comparison unit for re-comparing both images using the reconfigured threshold value.

  • Patent number: 9552636
    Abstract: Methods and systems for detecting defects on a wafer using defect-specific and multi-channel information are provided. One method includes acquiring information for a target on a wafer. The target includes a pattern of interest (POI) formed on the wafer and a known defect of interest (DOI) occurring proximate to or in the POI. The method also includes detecting the known DOI in target candidates by identifying potential DOI locations based on images of the target candidates acquired by a first channel of an inspection system and applying one or more detection parameters to images of the potential DOI locations acquired by a second channel of the inspection system. Therefore, the image(s) used for locating potential DOI locations and the image(s) used for detecting defects can be different.
