Abstract:
1. Charged particle system such as a multi beam lithography system, comprising a manipulator device for manipulation of one or more charged particle beams, wherein the manipulator device comprises: a planar substrate comprising at least one through opening in the plane of the planar substrate, wherein each through opening is arranged for passing at least one charged particle beam there through and each through opening is provided with electrodes arranged in a first set of multiple first electrodes along a first part of a perimeter of said through opening and in a second set of multiple second electrodes along a second part of said perimeter; and, an electronic control circuit arranged for providing voltage differences to pairs of electrodes, each pair being a first electrode from the first set and a second electrode from the second set, in dependence of a position of the first and second electrode along the perimeter of the through opening, to provide an electrical field that is substantially homogeneous across the through opening.
