摘要:
This invention relates to an electron optical system array having a plurality of electron lenses. The electron optical system array includes a plurality of electrodes arranged along the paths of a plurality of charged-particle beams. Each of the plurality of electrodes has a membrane in which a plurality of apertures are formed on the paths of the plurality of charged-particle beams, and a support portion which supports the membrane. At least two of the plurality of electrodes are arranged to form a nested structure.
