  • Publication number: 20230420216
    Abstract: Systems and methods for operating a combined laser and broad ion beam (BIB) polisher in a sample preparation workflow, are disclosed. An example method for operating a combined laser and broad ion beam (BIB) polisher according to the present invention comprises positioning a sample within the interior volume of the combined BIB and laser sample preparation system, causing a laser source component of the combined BIB and laser sample preparation system to emit an optical beam towards the sample, and causing a BIB source component of the combined BIB and laser sample preparation system to emit a broad ion beam towards the sample. The optical beam and the broad ion beam are each configured to cause a first portion and a second portion of the sample upon which it is incident to be removed, respectively.

  • Publication number: 20230375445
    Abstract: Systems and methods for operating a broad ion beam (BIB) polisher in a sample preparation workflow having improved uptime, are disclosed. An example method for operating a broad ion beam (BIB) polisher having improved uptime according to the present invention comprises causing a first BIB source to emit a first broad ion beam towards a sample positioned within an interior volume of the BIB polisher while the first BIB source is in emitting the first broad ion beam towards the sample, removing a second BIB source from the BIB polisher that is configured to emit a second broad ion beam towards the sample when in use.

  • Publication number: 20230377834
    Abstract: Systems and methods for pre-aligning samples for more efficient processing of multiple samples with a BIB system according to the present invention comprises affixing a sample to an adjustable portion of a sample holder, nesting the sample holder with a first mask having a first mask edge, wherein the first mask is positioned outside of a BIB system, and aligning the sample such that it has a desired geometric relationship to the first mask edge. The first mask may be geometrically similar with a second mask within the BIB system that has a second mask edge such that the geometric relationship between the first mask edge and the sample when the sample holder is nested with the first mask is the same as the geometric relationship between the second mask edge and the sample when the sample holder is nested with the second mask.

  • Publication number: 20230377833
    Abstract: Systems and methods for efficiently processing multiple samples with a BIB system, are disclosed. An example method for efficiently processing multiple samples with a BIB system according to the present invention comprises removing an individual sample holder containing a sample from a storage location within the BIB system, wherein the BIB system includes multiple sample holders positioned in one or more storage locations, loading the individual sample holder onto a sample stage configured to hold the sample holder during polishing of the corresponding sample held by the individual sample holder, and causing a BIB source to emit a broad ion beam towards the sample, wherein the broad ion beam removes at least a portion of the sample upon which it is incident. Once a desired portion of the sample is removed, the sample holder is removed from the sample stage and loaded back into the storage location.

  • Patent number: 9741527
    Abstract: A specimen holder for a Charged Particle Microscope is disclosed. The holder has a support structure with an elongated member including a specimen mounting zone. The specimen mounting zone comprises a rotor with an axis perpendicular to the elongated member with a paddle connected to it which may be rotated. Specimens may be mounted on the paddle so that rotation of the paddle allows specimens to be rotated and/or inverted for microscopic observation on both sides. Specimens may either be directly mounted on the paddle, or on a grid, half-moon grid, lift-out grid, aperture frame, dielectric film, etc.
