  • SEMICONDUCTOR MEASUREMENT APPARATUS
    Publication number: 20240125709
    Abstract: A semiconductor measurement apparatus includes an illuminator configured to output light having a first wavelength band and light having a second wavelength band, different from the first wavelength band, a stage on which a test object is positioned, a camera configured to receive light reflected or scattered from the test object or transmitted through the test object, and a controller configured to control the illuminator and the camera, and to measure, based on information indicated by the light received by the camera, a plurality of structures included in the test object. The controller is configured to set an exposure time of the camera to a first exposure time while the illuminator outputs the light having the first wavelength band, and to set the exposure time of the camera to a second exposure time, different from the first exposure time, while the illuminator outputs the light having the second wavelength band.
