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.

Abstract: A method and apparatus for producing thin lamella for TEM observation. The steps of the method are robust and can be used to produce lamella in an automated process. In some embodiments, a protective coating have a sputtering rate matched to the sputtering rate of the work piece is deposited before forming the lamella. In some embodiments, the bottom of the lamella slopes away from the feature of interest, which keeps the lamella stable and reduces movement during thinning. In some embodiments, a fiducial is used to position the beam for the final thinning, instead of using an edge of the lamella. In some embodiments, the tabs are completed after high ion energy final thinning to keep the lamella more stable. In some embodiments, a defocused low ion energy and pattern refresh delay is used for the final cut to reduce deformation of the lamella.

Abstract: A single column charged particle source with user selectable configurations operates in ion-mode for FIB operations or electron mode for SEM operations. Equipped with an x-ray detector, energy dispersive x-ray spectroscopy analysis is possible. A user can selectively configure the source to prepare a sample in the ion-mode or FIB mode then essentially flip a switch selecting electron-mode or SEM mode and analyze the sample using EDS or other types of analysis.

Abstract: The invention relates to a method of preparing and imaging a sample using a particle-optical apparatus, equipped with an electron column and an ion beam column, a camera system, a manipulator. The method comprises the steps of deriving a first ptychographic image of the sample from a first electron image, thinning the sample, and forming a second ptychographic image of the sample. In an embodiment of the invention the seed image used for the second image is the first ptychographic image. In another embodiment the second ptychographic image is the image of the layer removed during the thinning. In another embodiment the inner potential of the sample is determined and dopant concentrations are determined.
