Alrik van den Brom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9362084
    Abstract: The invention relates to a charged particle system for processing a target surface with at least one charged particle beam. The system comprises an optical column with a beam generator module for generating a plurality of charged particle beams, a beam modulator module for switching on and off said plurality of beams and a beam projector module for projecting beams or subbeams on said target surface. The system further comprises a frame supporting each of said modules in a fixed position and alignment elements for aligning at least one of beams and/or subbeams with a downstream module element.
    Type: Grant

  • Patent number: 8618496
    Abstract: A charged particle system such as a multi beam lithography system. A manipulator device manipulates one or more charged particle beams. The manipulator device includes at least one through opening in the plane of the planar substrate for passing at least one charged particle. Each through opening is provided with electrodes arranged in a first set of multiple first electrodes along a first part of a perimeter of the through opening and in a second set of multiple second electrodes along a second part of the perimeter. An electronic control circuit is arranged for providing voltage differences the electrodes in dependence of a position of the first and second electrode along the perimeter of the through opening.
