Abstract:
1. A method for locating a defect in a defect review process, comprising: using a processor included in a computer system to perform the steps of: acquiring an image and data from an inspection tool, wherein the image illustrates an area on a specimen in which a defect to be reviewed is located, and wherein the data indicates a position and features of the defect within the area; acquiring an additional image of the specimen proximate the position of the defect indicated in the data using an imaging subsystem of a defect review tool; identifying a portion of the additional image acquired using the imaging subsystem of the defect review tool that corresponds to the image acquired from the inspection tool, wherein said identifying comprises comparing, within a search window in the additional image, the image acquired from the inspection tool with different portions of the additional image acquired using the imaging subsystem of the defect review tool, wherein dimensions of the search window are larger than dimensions of the image, determining if multiple portions within the search window in the additional image correspond to the image, wherein dimensions of each of the multiple portions are the same as the dimensions of the image, and comparing the multiple portions that correspond to the image with each other at the position of the defect indicated in the data to identify the multiple portion in which the defect is located; and determining a position of the defect within the identified multiple portion of the additional image using the data.
