Abstract: 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.

Abstract: In a particle projection lithography system, an alignment system is used to determine alignment parameters to measure the position and shape of an optical image of a pattern of structures formed in a mask and imaged onto a target by means of a broad particle beam, by means of an apparatus with a plurality of alignment marks adapted to produce secondary radiation upon irradiation with radiation of said particle beam. In order to allow for a variation of the alignment parameters along the optical axis, the alignment marks are positioned outside the aperture of the alignment system for the part of the beam that generates said optical image, arranged at positions to coincide with particle reference beams projected through reference beam forming structures provided on the mask while said optical image is projected onto the target, and situated on at least two different levels over the target as seen along the directions of the respective reference beams.

Abstract: An electrostatic lens system consisting of several electrodes and a novel method of making same. The invention relates to a lithography apparatus that includes a field composable lens where at least one lens electrode has a novel structure, said structure comprising an outer support structure, an insulating intermediate part and a conductive inner part composed of a number of segment-like subelectrodes that can be individually powered, if necessary, slightly differently to produce desired individual electrostatic subfields to be superimposed to the lens field. With the field composable lens design, it has been successfully demonstrated that a number of shape and alignment errors of lens components can be corrected by supplying slightly different voltages to individual subelectrodes, thus optimizing the overall lens performance (in view of its optical properties). The lens components may be manufactured on less expensive and readily available conventional precision machinery rather than expensive and rarely available high precision equipment.
