    Abstract: The invention relates to a charged particle lithography system for transferring a pattern onto the surface of a target. The system comprises a beam generator, a beam stop array and a modulation device. The beam generator is arranged for generating a plurality of charged particle beamlets, the plurality of beamlets defining a column. The beam stop array has a surface for blocking beamlets from reaching the target surface and an array of apertures in the surface for allowing the beamlets to reach the target surface. The modulation device is arranged for modulating the beamlets to prevent one or more of the beamlets from reaching the target surface or allow one or more of the beamlets to reach the target surface, by deflecting or not deflecting the beamlets so that the beamlets are blocked or not blocked by the beam stop array. The modulation device comprises a plurality of apertures with associated modulators; and a plurality of light sensitive elements, both arranged in arrays. A surface area of the modulation device comprises an elongated beam area comprising an array of apertures and associated modulators, and a power interface area for accommodating a power arrangement for suitably powering elements within the modulation device. The power interface area being located alongside a long side of the elongated beam area and extending in a direction substantially parallel thereto.

    Abstract: An electron beam apparatus having an electron analyzer (28) is achieved which can control the illumination lens system (22) by feedback without adversely affecting the imaging action even if a specimen (23) is positioned within the magnetic field of the objective lens. The apparatus has an energy shift control module (37) for controlling energy shift. On receiving instructions about setting of energy shift from the CPU (36), the control module (37) issues an instruction for shifting the accelerating voltage to a specified value to an accelerating-voltage control module (33) . The control module also sends information about the energy shift to an energy shift feedback control module (38), which calculates the feedback value and supplies information about corrections of lenses and deflection coils to a TEM optics control module (34) . The feedback value is multiplied by a corrective coefficient that can be calibrated.
