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： A beam manipulating arrangement for a multi beam application using charged particles comprises a multi-aperture plate having plural apertures traversed by beams of charged particles. A frame portion of the multi-aperture plate is heated to reduce temperature gradients within the multi-aperture plate. Further, a heat emissivity of a surface of the multi-aperture plate may be higher in some regions as compared to other regions in view of also reducing temperature gradients.

摘要： A charged-particle multi-beam exposure apparatus (1) for exposure of a target (41) uses a plurality of beams of electrically charged particles, which propagate along parallel beam paths towards the target (41). For each particle beam an illumination system (10), a pattern definition means (20) and a projection optics system (30) are provided. The illuminating system (10) and/or the projection optics system (30) comprise particle-optical lenses having lens elements (L1, L2, L3, L4, L5) common to more than one particle beam. The pattern definition means (20) defines a multitude of beamlets in the respective particle beam, forming its shape into a desired pattern which is projected onto the target (41), by allowing it to pass only through a plurality of apertures defining the shape of beamlets permeating said apertures, and further comprises a blanking means to switch off the passage of selected beamlets from the respective paths of the beamlets.
