    Abstract: In a pattern-lock system of particle-beam apparatus wherein the imaging of the pattern is done by means of at least two consecutive projector stages of the projecting system, reference marks are imaged upon registering means to determine the position of the particle-beam, at the location of an intermediary image of the reference marks produced by a non-final projector stage, with the registering means being positioned at locations of nominal positions of an intermediary imaging plane. Furthermore, to produce a scanning movement over the registering means the reference beamlets are shifted laterally by means of deflector means provided in the pattern defining means in dependence of a time-dependent electric voltage.

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

    Abstract: In an ion projection lithography system, apparatus and methods for positioning on a substrate or wafer at a target station an image of structures provided on a mask, wherein the mask includes reference marks to provide ion reference beams about the image field, the target station includes marks and the beam of the system is controlled to establish a coincidence of the marks on the mask with the corresponding marks at the target station. The ion projection system shown includes in this optical path an electrostatic multipole, means for rotational adjustment of the image relative to the substrate, and means for correcting the scale of the image. Embodiments are shown in which the marks at the target station are carried on the wafer or on a reference block which is positionally related to the wafer, e.g., by an interferometer. In the case of the reference block, it has an aperture corresponding in size to the mask image to be formed on the substrate so that the marks are disposed outside the optical path used to generate the image on the substrate. Detectors provided for secondary radiation emitted by the marks at the target station as a result of the ion reference beams passing through the marks on the mask produce signals that control the multipole, the means for relative rotational adjustment of the image on the substrate and the means for scale correction. Special masks are provided that enable the reference beams to reach their respective marks at the target station during blanking and unblanking of the mask, permitting operation of the alignment system at both times. The reference beams are shielded from the image beam and are scanned repeatedly over their respective marks at the target station.

    Abstract: The invention concerns an ion beam apparatus, by means of which defects in a substrate can be recognized, and repaired under continuous control. For this purpose, the ion beam apparatus, in its beams path, after the ion source, is equipped with a mask exhibiting a preferrably circular hole and between ion source and mask with a controllable lens for the purpose of modification of the divergence angle under which the beam strikes the mask. The aperture of the mask is imaged upon the substrate. In this way the intensity of the ion beam may be varied for use in inspecting a substrate for defects and subsequently removing the detected defects.

    Abstract: 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.
