Beschreibung
Zusammenfassung:	An apparatus for finishing patterns, for example, masks for chip manufacture is provided with an ion source the ion beam current strength of which can be adjusted at a comparatively low value for removing material therewith, for restoring opaque defects, and at a comparatively high current value for the deposition of material from the ion beam as such, for restoring clear defects. Particles which are not desired for the working can be removed from the ion beam by means of a particle discriminator.
