  • Patent number: 10615002
    Abstract: Processes may be performed with a plurality of FIB-SEM systems. A first process group includes recording an image with the electron beam column, depositing material with supply of a process gas, and performing ion beam etching. A second process group includes performing a sample exchange, exchanging a reservoir of a gas source for the process gas, and verifying an image that was recorded with the electron beam column. The processes of the second group are prioritized. The FIB-SEM systems are actuated to work through processes contained in process lists. If in a plurality of FIB-SEM systems processes of the second group are to be performed simultaneously, an instruction based on the prioritization is output to the user.

  • Patent number: 9685300
    Abstract: A method is provided for processing and/or observing an object using at least one particle beam that is scanned over the object. A scan region on the object is determined, the scan region having scan lines, and the particle beam is moved in a first scanning direction along one of the scan lines. The first scanning direction is changed to a second scanning direction at a change-of-direction time. Changing from the first scanning direction to the second scanning direction comprises setting of a point of rotation in that scan line of the scan region in which the particle beam is situated at the change-of-direction time, with an axis of rotation extending through the point of rotation. The first scanning direction is changed into the second scanning direction by rotating the scan region about the axis of rotation, with the point of rotation being selected dependent on the direction of rotation.
