Abstract
A wafer inspection system includes a controller in communication with an electron-beam inspection tool. The controller includes circuitry to: acquire, via an optical imaging tool, coordinates of defects on a sample; set a Field of View (FoV) of the electron-beam inspection tool to a first size to locate a subset of the defects; determine a position of each defect of the subset of the defects based on inspection data generated by the electron-beam inspection tool during a scanning of the sample; adjust the coordinates of the defects based on the determined positions of the subset of the defects; and set the FoV of the electron-beam inspection tool to a second size to locate additional defects based on the adjusted coordinates.
