Patent number: 10928620Abstract: A microscope system includes an observation optical system including an objective lens, an XY stage capable of moving an XY plane in an X-axis direction and an Y-axis direction, a first change unit configured to change a slant of the XY plane with respect to an optical axis direction of the objective lens, and a second change unit configured to change a slant of a slide placed on the XY stage with respect to the XY plane. Changing the slant of the XY plane by the first change unit is performed based on a first mark arranged on the XY plane at a position observable by the observation optical system. Changing the slant of the slide with respect to the XY plane by the second change unit is performed based on a second mark arranged on the slide.Type: GrantFiled: December 7, 2016Date of Patent: February 23, 2021Assignee: Canon Kabushiki KaishaInventors: Michiie Sakamoto, Akinori Hashiguchi, Shinobu Masuda, Tsuguhide Sakata, Tsutomu Shimada, Hirotake Ando, Kazuhiko Kato

Patent number: 10903040Abstract: A composite charged particle beam apparatus includes a first charged particle beam column that irradiates a thin sample with a first charged particle beam, a second charged particle beam column that irradiates an irradiation position of the first charged particle beam of the thin sample with a second charged particle beam, a sample holder that fixes the thin sample, and a sample stage on which the sample holder is mounted. The sample holder is able to rotate the thin sample within a surface parallel to an observation surface of the thin sample around a first rotational axis on the sample stage.Type: GrantFiled: May 1, 2019Date of Patent: January 26, 2021Inventors: Hiroyuki Suzuki, Shinya Kitayama

Patent number: 10867782Abstract: A metallic plate holder 3 is directly placed on a flat bottom plate 1a of a sample chamber. A linear guide 21 extending in x-direction is located below the bottom plate. Another linear guide 22 extending in y-direction is fixed to a movable part 21a of the linear guide 21. A magnet 23, fixed to a movable part 22a of the linear guide 22, magnetically attracts the plate holder across the bottom plate. When the magnet is two-dimensionally driven by the linear guides, the plate holder follows it and moves two-dimensionally. The flat bottom plate limits the z-position of the plate holder, thereby reducing the fluctuation in the level of the sample on a sample plate 2 due to the movement. Thus, the variation in the level at different positions on the sample plate is reduced, so that the number of times of a calibrant measurement can be decreased.Type: GrantFiled: January 10, 2019Date of Patent: December 15, 2020Assignee: SHIMADZIJ CORPORATIONInventors: Kei Kodera, Masaji Furuta

Patent number: 10819205Abstract: Aspects of the invention provide methods and systems for moving a plurality of moveable stages relative to a stator. The stator comprises a plurality of coils shaped to provide pluralities of coil trace groups where each coil trace group comprises a corresponding plurality of generally linearly elongated coil traces which extend across a stator tile. Each moveable stage comprises a plurality of magnet arrays. Methods and apparatus are provided for moving the moveable stages relative to the stator, where a magnet array from a first moveable stage and a magnet array from a second moveable stage both overlap a shared group of coil traces. For at least a portion of the time that the magnet arrays from the first and second moveable stages overlap the shared group of coil traces, currents are controllably driven in the shared coil trace group based on the positions of both the first and second moveable stages. The positions of the first and second moveable stages may be ascertained by feedback.Type: GrantFiled: May 31, 2019Date of Patent: October 27, 2020Assignee: The University of British ColumbiaInventor: Xiaodong Lu

Patent number: 10699870Abstract: A sample carrier capable of preventing damage to a support stage on which a sample holder is placed while ensuring a sufficient level of conveyance speed includes a sample holder, a holder mounting member, and a transport portion. The transport portion has a drive source (constant-speed motor), a rotary member (second toothed wheel), a guide portion (linear guide), and a rod. The rotary member is rotated about its axis of rotation by the drive source. The guide portion operates to guide the holder mounting member in a linear direction perpendicular to the axis of rotation of the rotary member. The rod is rotatably coupled to the rotary member and to the holder mounting member and has a coupled portion coupled to the rotary member. At a midpoint of the range of movement of the holder mounting member, the shortest distance from the coupled portion to the guide portion is greatest.Type: GrantFiled: August 5, 2019Date of Patent: June 30, 2020Assignee: JEOL Ltd.Inventor: Shuho Yoshida
