Publication number: 20250095953Abstract: Methods and systems for performing sample lift-out and creating attachments for highly reactive materials within charged particle microscopy systems are disclosed herein. Methods include creating attachments between a sample manipulator and a sample within a charged particle system and translating a sample manipulator so that the sample manipulator is proximate to a sample such that a portion of the sample manipulator proximate to the sample is composed of a high sputter yield material. The methods and systems include milling, with a charged particle beam, the high sputter yield material such that portions of the high sputter yield material are removed from the sample manipulator without milling away material from the sample such that at least some of the removed high sputter yield material redeposits to form an attachment between the sample manipulator and the sample without milling material away from the sample.Type: ApplicationFiled: December 5, 2024Publication date: March 20, 2025Inventors: Adam STOKES, Cliff BUGGE, Brandon VAN LEER, Valerie BROGDEN, Chengge JIAO, Letian LI, David DONNET

Patent number: 12165832Abstract: Methods and systems for performing sample lift-out and protective cap placement for highly reactive materials within charged particle microscopy systems are disclosed herein. Methods include preparing a nesting void in a support structure, translating at least a portion of a sample into the nesting void, and milling material from a region of the support structure that defines the nesting void. The material from the region of the support structure is milled such that at least some of the removed material redeposits to form an attachment bond between the sample and a remaining portion of the support structure. In various embodiments, the sample can then be investigated using one or more of serial sectioning tomography on the sample, enhanced insertable backscatter detector (CBS) analysis on the sample, and electron backscatter diffraction (EBSD) analysis on the sample.Type: GrantFiled: December 31, 2021Date of Patent: December 10, 2024Assignee: FEI CompanyInventors: Adam Stokes, Cliff Bugge, Brandon Van Leer, Valerie Brogden, Chengge Jiao, Letian Li, David Donnet

Patent number: 10825651Abstract: Techniques are described that facilitate automated extraction of lamellae and attaching the lamellae to sample grids for viewing on transmission electron microscopes. Some embodiments of the invention involve the use of machine vision to determine the positions of the lamella, the probe, and/or the TEM grid to guide the attachment of the probe to the lamella and the attachment of the lamella to the TEM grid. Techniques that facilitate the use of machine vision include shaping a probe tip so that its position can be readily recognized by image recognition software. Image subtraction techniques can be used to determine the position of the lamellae attached to the probe for moving the lamella to the TEM grid for attachment. In some embodiments, reference structures are milled on the probe or on the lamella to facilitate image recognition.Type: GrantFiled: May 13, 2019Date of Patent: November 3, 2020Assignee: FEI CompanyInventors: Valerie Brogden, Jeffrey Blackwood, Michael Schmidt, Dhruti Trivedi, Richard J. Young, Thomas G. Miller, Brian Roberts Routh, Jr., Stacey Stone, Todd Templeton

Patent number: 9218940Abstract: Methods, apparatuses, and systems for slice and view processing of samples with dual beam systems. The slice and view processing includes exposing a vertical wall of a trench formed in a sample surface; capturing a first image of the wall by interrogating the wall with an interrogating beam while the wall is at a first orientation relative to the beam; capturing a second image of the wall by interrogating the wall with the beam while the wall is at a second orientation relative to the beam, wherein first distances in the first image between a reference point and surface points on the wall are different than second distances in the second image between the reference point and the surface points; determining elevations of the surface points using the first distances and the second distances; and fitting a curve to topography of the wall using the elevations.Type: GrantFiled: May 30, 2014Date of Patent: December 22, 2015Assignee: FEI CompanyInventor: Valerie Brogden
