    Abstract: An electrostatic charged particle beam lens includes an electrode including a flat plate having a first surface having a normal line extending in a direction of an optical axis and a second surface opposite to the first surface, the electrode having a through-hole extending from the first surface to the second surface. A circularity in a first region that is on the first surface side and a circularity in a second region that is on the second surface side are each better than a circularity in a third region that is a region in the electrode disposed between the first surface and the second surface.

    Abstract: Apparatus and method for projection ion beam lithography are described which allow formation of low distortion, large field, reduced images of a mask pattern at a wafer plane using an optical column of practical size. The column shown is comprised of an accelerating Einzel lens followed by a gap lens, with numerous cooperating features. By coordinated selection of the parameters of the optical column, lens distortion and chromatic blurring are simultaneously minimized. Real time measurement of the position of the image field with respect to the existing pattern on the wafer is employed before and during the time of exposure of the new field and means are provided to match the new field to the existing pattern even when the latter has been distorted by processing. A metrology system enables convenient calibration and adjustment of the apparatus.

    Abstract: An electrostatic charged particle beam lens includes an electrode including a flat plate having a first surface having a normal line extending in a direction of an optical axis and a second surface opposite to the first surface, the electrode having a through-hole extending from the first surface to the second surface. When an opening cross section is defined as a cross section of the through-hole taken along a plane perpendicular to the normal line and a representative diameter is defined as a diameter of a circle obtained by performing regression analysis of the opening cross section, a representative diameter of the opening cross section in a first region that is on the first surface side and a representative diameter of the opening cross section in a second region that is on the second surface side are smaller than a representative diameter of the opening cross section in a third region that is a region in the electrode disposed between the first surface and the second surface.
