  • Patent number: 10629405
    Abstract: An electron beam device suitable for observing the bottom of a deep groove or hole with a high degree of accuracy under a large current condition includes: an electron optical system having an irradiation optical system to irradiate a first aperture with an electron beam emitted from an electron source and a reduction projection optical system to project and form an aperture image of the first aperture on a sample, detectors to detect secondary electrons emitted by irradiating the sample with the electron beam through the electron optical system. An image processing unit generates a two-dimensional image from detection signals obtained by irradiating the sample while the electron beam scans the sample two-dimensionally by scanning deflectors of the electron optical system. Further, generates a reconstructed image by deconvoluting electron beam intensity distribution information of an ideal aperture image of the first aperture from the generated two-dimensional image information.
