Patent number: 10636621Abstract: A charged particle beam device wherein a transmission image corresponding to an arbitrary diffraction spot or a diffraction pattern corresponding to a partial range in the transmission image are easily and automatically captured. A charged particle beam device having: an image-capturing unit for forming an image of a sample; a diaphragm disposed in the image-capturing unit, a plurality of openings having different sizes for transmitting an electron beam from the sample being formed in the diaphragm; a movement unit for varying the position of the diaphragm; and a display unit for displaying the formed image, wherein when the operator selects, e.g., a diffraction spot (A) on the display unit, the movement unit moves the diaphragm from the positional relationship between the diaphragm and the image in accordance with the position of the diffraction spot (A).Type: GrantFiled: April 14, 2015Date of Patent: April 28, 2020Assignee: Hitachi High-Technologies CorporationInventors: Akinari Hanawa, Hideki Kikuchi, Yoshifumi Taniguchi, Toshie Yaguchi, Takashi Dobashi, Keitaro Watanabe, Hirokazu Tamaki

Patent number: 10535497Abstract: An electron microscope for observation by illuminating an electron beam on a specimen, includes: an edge element disposed in a diffraction plane where a direct beam not diffracted by but transmitted through the specimen converges or a plane equivalent to the diffraction plane; and a control unit for controlling the electron beam or the edge element. The edge element includes a blocking portion for blocking the electron beam, and an aperture for allowing the passage of the electron beam. The aperture is defined by an edge of the blocking portion in a manner that the edge surrounds a convergence point of the direct beam in the diffraction plane. The control unit varies contrast of an observation image by shifting, relative to the edge, the convergence point of the direct beam along the edge while maintaining a predetermined distance between the convergence point of the direct beam and the edge.Type: GrantFiled: August 22, 2016Date of Patent: January 14, 2020Assignee: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Hirokazu Tamaki, Ken Harada, Keiji Tamura, Yoshifumi Taniguchi, Hiroto Kasai, Toshie Yaguchi, Takafumi Yotsuji

Patent number: 9679738Abstract: The present invention relates to a lens-less Foucault method wherein a transmission electron microscope objective lens (5) is turned off, an electron beam crossover (11, 13) is matched with a selected area aperture (65), and the focal distance of a first imaging lens (61) can be changed to enable switching between a sample image observation mode and a sample diffraction pattern observation mode, characterized in that a deflector (81) is disposed in a stage following the first imaging lens (61), and conditions for an irradiating optical system (4) can be fixed after conditions for the imaging optical system have been determined. This allows a lens-less Foucault method to be implemented in a common general-use transmission electron microscope with no magnetic shielding lens equipped, without burdening the operator.Type: GrantFiled: May 16, 2014Date of Patent: June 13, 2017Assignee: Hitachi High-Technologies CorporationInventors: Hiroaki Matsumoto, Takeshi Sato, Yoshifumi Taniguchi, Ken Harada

Patent number: 9558910Abstract: A sample holder for an electron microscope has multiple sample stands, can allow at least one sample stand to move, and enables multiple samples for a transmission electron microscope to be prepared by a focused ion beam apparatus. A holder tip opening is provided in a tip of the sample holder. A back end of the sample holder has a knob, a rolling mechanism, a coarse adjustment mechanism, and a connector. By pressing the knob, fixation of the rolling mechanism is canceled, and the back end from the rolling mechanism and the tip of the sample holder will rotate. This rolling mechanism enables arrangement of the samples to be rotated in both the observing of a sample and the preparing of a sample for a transmission electron microscope with the focused ion beam apparatus. Moreover, the sample stand is movable by the coarse adjustment mechanism and the fine adjustment mechanism.Type: GrantFiled: December 3, 2012Date of Patent: January 31, 2017Assignee: Hitachi High-Technologies CorporationInventors: Shohei Terada, Yoshifumi Taniguchi, Yasuhira Nagakubo
