Abstract:
A method of manufacturing an array structure having a plurality of openings and a plurality of pairs of opposing electrodes which are arranged in correspondence with each of the plurality of openings to control loci of a plurality of charged particle beams that pass through the plurality of openings, respectively, comprising:a trench formation step of forming a plurality of pairs of opposing trenches in a substrate; a side-surface insulating layer formation step of forming an insulating layer on a side surface of each of the plurality of pairs of opposing trenches; a process step of processing the plurality of pairs of trenches to expose a conductive layer to a bottom portion of each of the plurality of pairs of opposing trenches; an electrode formation step of selectively growing a conductive material on the conductive layer exposed to the bottom portion of each of the plurality of pairs of trenches to fill the plurality of pairs of trenches with the conductive material, thereby forming a plurality of pairs of opposing electrodes; and an opening formation step of forming an opening between each of the pairs of opposing electrodes.
