  • Patent number: 9349570
    Abstract: An improved method and apparatus for extracting and handling samples for S/TEM analysis. Preferred embodiments of the present invention make use of a micromanipulator and a hollow microprobe probe using vacuum pressure to adhere the microprobe tip to the sample. By applying a small vacuum pressure to the lamella through the microprobe tip, the lamella can be held more securely and its placement controlled more accurately than by using electrostatic force alone. By using a probe having a beveled tip and which can also be rotated around its long axis, the extracted sample can be placed down flat on a sample holder. This allows sample placement and orientation to be precisely controlled, thus greatly increasing predictability of analysis and throughput.

  • Patent number: 8399864
    Abstract: A dual beam system includes an ion beam system and a scanning electron microscope with a magnetic objective lens. The ion beam system is adapted to operate optimally in the presence of the magnetic field from the SEM objective lens, so that the objective lens is not turned off during operation of the ion beam. An optional secondary particle detector and an optional charge neutralization flood gun are adapted to operate in the presence of the magnetic field. The magnetic objective lens is designed to have a constant heat signature, regardless of the strength of magnetic field being produced, so that the system does not need time to stabilize when the magnetic field is changed.

  • Patent number: 7511282
    Abstract: Methods of extracting a TEM sample from a substrate include milling a hole on the sample and inserting a probe into the hole. The sample adheres to the probe, and can be processed on transferred while on the probe. In another embodiment, the sample is freed from a substrate and adheres to a probe by electrostatic attraction. The sample is placed onto a TEM sample holder in a vacuum chamber.
