  • Patent number: 11476080
    Abstract: A device comprises an electron column or an ion column, provided with an adjustable holder. The adjustable holder maintains the whole range of movements of the manipulation stage and is adapted to change its position in relation to the stage at least in one direction, wherein the range of movements of the manipulation stage is sufficient to change this position and it is unnecessary to install any other control drive or actuator.

  • Publication number: 20210050180
    Abstract: A device for creating and placing a lamella comprises a focused ion beam, a scanning electron microscope, a stage for placing at least two specimens enabling tilting, rotation and movement of the specimen. The device further comprises a manipulator terminated by a needle for attaching and transporting the specimen. The manipulator is positioned in a plane perpendicular to the axis of the tilt of the specimen, thereby enabling easy transportation and placing of the lamella into the specimen holder for a transmission electron microscope, so-called grid. The manipulator is adjusted to rotate the needle about its own axis. Thus, it enables inverting of the lamella and its polishing over a layer of semiconductor substrate, on which a semiconductor structure is formed, in case of creating the lamella from a semiconductor device.
