  • Publication number: 20230215683
    Abstract: 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.

  • Patent number: 10825651
    Abstract: 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.

  • Patent number: 9281163
    Abstract: A TEM grid provides posts having steps, the steps increasing the number of samples that can be attached to the grid. In some embodiments, each post includes a one sided stair step configuration. A method of extracting multiple samples includes extracting samples and attaching the samples to the different stair steps on the posts.

  • Patent number: 9218940
    Abstract: 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.
