    Abstract: In a particle-optical imaging lithography system, an illuminating system comprising a particle source and a first electrostatic lens arrangement produces a particle beam which penetrates a mask foil provided with an orifice structure positioned in the particle beam path. This structure is imaged on a substrate plane by a projection system comprising a second electrostatic lens arrangement. The first and second lens arrangements each comprise, on their respective sides facing the mask holding device, at least one pre- and post-mask electrode, respectively. By applying different electrostatic potentials to the pre- and post-mask electrodes and to the mask foil, the mask foil and the pre-mask electrode form a grid lens with negative refracting power, and the mask foil and the post-mask electrode also form a grid lens with negative refracting power.

    Abstract: A charged particle, in particular ion projector system, has a mask arranged in the path of the charged particle beam and provided with transparent spots, in particular openings, arranged asymmetrically to the optical axis, which are reproduced on a wafer by means of lenses arranged in the path of the charged particle beam. The charged particle beam has at least one cross-over (crosses the optical axis at least once) between the mask and the wafer. Charged particles with an opposite charge to the charge of the reproduction particles are supplied into the path of the reproduction charged particle beam in a defined area located between the mask and the wafer. The limits that define said area are selected in such a way that the absolute value of the integral effect of the space charge on the particles that reproduce the mask structures is as high upstream of said area (seen in the direction of radiation) as the absolute value of the integral effect of the space charge downstream of said area.
