  • Patent number: 10541104
    Abstract: A method and a charged particle beam system that includes charged particle beam optics and a movable stage; wherein the movable stage is configured to introduce a movement between the object and charged particle beam optics; wherein the movement is of a constant velocity and along a first direction; wherein the charged particle beam optics is configured to scan, by the charged particle beam, multiple areas of the object so that each point of the multiple areas is scanned multiple times; wherein the multiple areas partially overlap; wherein the scanning is executed by the charged particle beam optics; wherein the scanning comprises performing counter-movement deflections of the charged particle beam for at least partially compensating for the movement; and wherein each area of the multiple areas is scanned by following an area scan scheme that defines multiple scan lines that differ from each other.

  • Patent number: 10249472
    Abstract: A charged particle beam device is described, which includes: a beam source configured to generate a charged particle beam propagating along an optical axis (A); an aperture device with a first number of apertures configured to create a first number of beamlets from the charged particle beam, wherein the first number is five or more, wherein the apertures are arranged on a ring line around the optical axis (A) such that perpendiculars of the apertures onto a tangent of the ring line are evenly spaced. The charged particle beam device further includes an electrostatic multipole device configured to individually influence the beamlets. Further, a charged particle beam influencing device and a method of operating a charged particle beam device are described.

  • Patent number: 7759642
    Abstract: A method for focusing a scanning microscope, including scanning a primary charged particle beam across first sites of a reference die of a wafer, detecting a secondary beam emitted from the sites, and computing first focus scores for the sites based on the secondary beam. The method includes scanning the primary beam across second sites of a given die of the wafer while modulating a focal depth of the primary beam, the reference die and the given die having congruent layouts, the second sites corresponding vectorially in location with the first sites, and detecting the secondary beam emitted from the second sites in response to the primary beam. The method also includes computing second focus scores for the second sites based on the detected secondary beam emitted therefrom, and determining an exact focus of the primary beam for the second sites using the first and the second focus scores.
