Patent number: 10340117Abstract: Since a diffraction phenomenon occurs in the electron beam passing through a differential evacuation hole, an electron beam whose probe diameter is narrowed cannot pass through a hole having an aspect ratio of a predetermined value or more, and accordingly, a degree in vacuum on the electron beam side cannot be improved. By providing a differential evacuation hole with a high aspect ratio in an ion beam device, it becomes possible to obtain an observed image on a sample surface, with the sample being placed under the atmospheric pressure or a pressure similar thereto, in a state where the degree of vacuum on the ion beam side is stabilized. Moreover, by processing the differential evacuation hole by using an ion beam each time it is applied, both a normal image observation with high resolution and an image observation under atmospheric pressure or a pressure similar thereto can be carried out.Type: GrantFiled: September 29, 2014Date of Patent: July 2, 2019Assignee: Hitachi, Ltd.Inventors: Shinichi Matsubara, Hiroyasu Shichi, Takashi Ohshima

The image formed by this sensor can then be used to manually, or automatically in an open or closed loop configuration, adjust the positioning of one or more charged-particle beams or optical beams to achieve coincidence of such beams or focus of one or more such beams.Type: GrantFiled: December 8, 2017Date of Patent: January 8, 2019Assignee: Waviks, Inc.Inventors: Thomas M. Moore, Gregory A. Magel

Patent number: 10175382Abstract: A method of radiological examination of an object for the identification and detection of the composition the object comprising the steps of: irradiating an object under test with high energy radiation such as x-rays or gamma-rays and collecting radiation emergent from the object at a suitable detector system in such manner that emergent radiation intensity data is collected for the entire volume of the object under test; numerically processing the radiation intensity data to obtain a first data item correlated to the total number of electrons within the sample; applying an alternative method to obtain a second data item correlated to another property of the sample; using the first and second data items to derive an indication of the material content of the sample.Type: GrantFiled: November 11, 2013Date of Patent: January 8, 2019Assignee: Kromek LimitedInventors: Ian Radley, Benjamin John Cantwell, Andrew Keith Powell

Patent number: 10168261Abstract: A heated or cooled sample holding stage for use in a nanoindentation measurement system is described. The geometry of the design and the selection of materials minimizes movement of a sample holder with respect to a nanoindentation tip over a wide range of temperatures. The system controls and minimizes motion of the sample holder due to the heating or cooling of the tip holder and/or the sample holder in a high temperature nanoindentation system. This is achieved by a combination of geometry, material selection and multiple sources and sinks of heat. The system is designed to control both the steady state and the transient displacement response.Type: GrantFiled: March 22, 2016Date of Patent: January 1, 2019Assignee: KLA-Tencor CorporationInventors: Warren Oliver, Sudharshan Phani Pardhasaradhi, Richard Anthony

Patent number: 10157724Abstract: In a scanning electron microscope, an atmospheric pressure space having a specimen arranged therein and a vacuum space arranged on a charged particle optical system side are isolated from each other using an isolation film that transmits charged particle beams. The scanning electron microscope has an electron optical lens barrel, a chassis, and an isolation film. The electron optical lens barrel radiates a primary electron beam onto a specimen. The chassis is directly bonded to the inside of the electron optical lens barrel and has an inside that turns into a lower vacuum state than the inside of the electron optical lens barrel at least during the radiation of the primary electron beam. The isolation film isolates a space in an atmospheric pressure atmosphere having a specimen mounted therein and the inside of the chassis in a lower vacuum state, and transmits the primary charged particle beam.Type: GrantFiled: December 27, 2017Date of Patent: December 18, 2018Assignee: Hitachi High-Technologies CorporationInventors: Shinsuke Kawanishi, Yusuke Ominami

Patent number: 10141157Abstract: In a device for performing observation with a charged particle microscope at an atmospheric pressure using a diaphragm, while there was a demand that a distance between the diaphragm and a sample be reduced as much as possible, there was a problem that a limit for how close the diaphragm and the sample can be brought to each other was unknown in the past. In the present invention, a height adjustment member is used, and the position of a diaphragm in a charged particle beam device with respect to the height adjustment member is defined as the specific point of an optical device, so that the positional relationship between the height adjustment member and the diaphragm in the optical device is reproduced, and the height of a sample table with a Z-axis driving mechanism is adjusted so as to locate the surface of the sample at the position of the specific point of the optical device.Type: GrantFiled: June 29, 2015Date of Patent: November 27, 2018Assignee: Hitachi High-Technologies CorporationInventors: Makoto Nakabayashi, Yuusuke Oominami, Shinsuke Kawanishi

Patent number: 10137642Abstract: Methods to form cross-linked or sintered objects include forming walls for reservoir layers, with cross-linkable or sinterable materials deposited in the reservoir layers. The cross-linkable or sinterable materials can then be cross-linked, e.g., changing the structure of the deposited cross linkable materials, or sintered, e.g., heat treated to fused the sinterable materials together. The walls for the reservoir layers can be removed after the objects are formed.Type: GrantFiled: May 5, 2015Date of Patent: November 27, 2018Inventors: Karl Joseph Gifford, Daniel Joseph Hutchison, Tai Dung Nguyen, Tue Nguyen

Patent number: 10140772Abstract: Embodiments are directed to visualizing electromagnetic (EM) particle emissions in a computer-generated virtual environment. In one scenario, a computer system accesses portions of data representing EM particle emissions emitted by a virtualized EM particle emitter. The computer system generates a particle visualization that includes at least a portion of the EM particle emissions being emitted from the virtualized EM particle emitter within the virtual environment. The particle visualization includes an indication of the EM particle emissions' interactions with other virtual or non-virtual elements in the virtual environment. The computer system then presents the generated particle visualization in the computer-generated virtual environment. In some cases, the computer system further receives user input intended to interact with virtual elements within the virtual environment.Type: GrantFiled: September 16, 2016Date of Patent: November 27, 2018Assignee: L3 Technologies, Inc.Inventors: Nathan H.
