Patent ID: 10242842

Abstract:
A method for cross-section processing and observation, and apparatus therefor, includes performing a position information obtaining process of observing the entirety of a sample by using an optical microscope or an electron microscope, and obtaining three-dimensional position coordinate information of a particular observation target object included in the sample; performing a cross-section processing process of irradiating a particular region in which the object is present by using a focused ion beam based on the information, and exposing a cross section of the region; performing a cross-section image obtaining process of irradiating the cross section by using an electron beam, and obtaining a cross-section image of a predetermined size region including the object; and performing a three-dimensional image obtaining process of repeating the cross-section processing process and the cross-section image obtaining process at predetermined intervals in a predetermined direction, and obtaining a three-dimensional image from the multiple cross-section images.
