    摘要: A method of modifying a sample surface layer in the vacuum chamber of a particle-optical apparatus, the method performed in vacuum, the method comprising: Providing the microscopic sample attached to a manipulator, Providing a first liquid at a first (controlled) temperature, Dipping the sample in the first liquid, thereby causing a sample surface modification, Removing the sample from the first liquid, Providing a second liquid at a second (controlled) temperature, Dipping the sample in the second liquid, and Removing the sample from the second liquid. This enables the wet processing of a sample in-situ, thereby enhancing speed and/or avoiding subsequent alteration/contamination of the sample, such as oxidation, etc. The method is particularly useful for etching a lamella after machining the lamella with a (gallium) FIB to remove the surface layer where gallium implantation occurred, or where the crystal lattice is disturbed.

    摘要: A method is provided, along with a corresponding apparatus, for filling a high aspect ratio hole without voids or for producing high aspect ratio structures without voids. A beam having a diameter smaller than the diameter of the hole is directed into the hole to induced deposition beginning in the center region of the hole bottom. After an elongated structure is formed in the hole by the beam-induced deposition, a beam can then be scanned in a pattern at least as large as the hole diameter to fill the remainder of the hole. The high aspect ratio hole can then be cross-sectioned using an ion beam for observation without creating artefacts. When electron-beam-induced deposition is used, the electrons preferably have a high energy to reach the bottom of the hole, and the beam has a low current, to reduce spurious deposition by beam tails.

    摘要: Optimized blending mode for mineralogy images. A luminosity value is determined for a pixel in a base layer or top layer mineralogy image. An image weighting value is determined from the luminosity value and an optional mixing parameter. A multiply value is determined by multiplying the base and top layer pixel values. An overlay value is determined from twice the multiply value if the value of one of the base layer or top layer pixel values is over a threshold, otherwise it is determined by inverting twice the product of the inverted top layer pixel value with the inverted base layer pixel value. A blended image pixel value is determined by adding the multiply value weighted with the image weighting value and the overlay value weighted with the inverted image weighting value.
