Abstract:
1. A method for producing a specimen for electron microscopy, comprising: guiding at least three stationary ion beams onto a specimen surface of the specimen at predetermined angles with respect to one another such that the at least three stationary ion beams at least contact or intersect one another on the specimen surface and form a zone of incidence at the specimen surface, wherein the specimen is cut out of a solid-state material with the specimen surface fowled thereon; and treating the specimen surface with the at least three stationary ion beams such that material of the specimen at an area of the zone of incidence is removed from the specimen surface by etching until a desired viewing surface is uncovered in the area of the zone of incidence, wherein the desired viewing surface is configured to allow viewing in a desired area of the specimen with an electron microscope, and wherein both the specimen and the at least three stationary ion beams are not moved such that the at least three stationary ion beams are operated stationarily during said treating of the specimen surface.
