摘要： In a particle-optical projection system (32) a pattern (B) is imaged onto a target (tp) by means of energetic electrically charged particles. The pattern is represented in a patterned beam (pb) of said charged particles emerging from the object plane through at least one cross-over (c); it is imaged into an image (S) with a given size and distortion. To compensate for the Z-deviation of the image (S) position from the actual positioning of the target (tp) (Z denotes an axial coordinate substantially parallel to the optical axis cx), without changing the size of the image (S), the system comprises a position detection means (ZD) for measuring the Z-position of several locations of the target (tp), a control means (33) for calculating modifications (cr) of selected lens parameters of the final particle-optical lens (L2) and controlling said lens parameters according to said modifications.

摘要： 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.
