  • Patent number: 8203119
    Abstract: The invention provides a charged particle beam device to inspect or structure a specimen with a primary charged particle beam propagating along an optical axis; a beam tube element having a tube voltage; and a retarding field analyzer in the vicinity of the beam tube element to detect secondary charged particles generated by the primary charged particle beam on the specimen. According to the invention, the retarding field analyzer thereby comprises an entrance grid electrode at a second voltage; at least one filter grid electrode at a first voltage; a charged particle detector to detect the secondary charged particles; and at least one further electrode element arranged between the entrance grid electrode and the at least one filter grid electrode. The at least one further electrode element reduces the size of the stray fields regions in the retarding electric field region to improve the energy resolution of the retarding field analyzer.

  • Patent number: 7075075
    Abstract: The invention provides a deflecting system for deflecting a charged particle beam from a first direction to a second direction, the deflecting system comprising a first deflector for deflecting said charged particle beam off the first direction within a first deflection plane; a second deflector for deflecting the deflected charged particle beam into the second direction within the first deflection plane; and at least one deflecting pair of correcting coils comprising two correction coils which is positioned and shaped to reduce an astigmatism of the charged particle beam caused by the deflections.

  • Patent number: 6943349
    Abstract: The present invention provides an improved column for a charged particle beam device. The column comprises an aperture plate having multiple apertures to produce multiple beams of charged particles and a deflector to influence the beams of charged particles so that each beam appears to come from a different source. Furthermore, an objective lens is used in order to focus the charged-particle beams onto the specimen. Due to the deflector, multiple images of the source are created on the surface of the specimen whereby all the images can be used for parallel data acquisition. Accordingly, the speed of data acquisition is increased. With regard to the focusing properties of the objective lens, the beams of charged particles can basically be treated as independent particle beams which do not negatively affect each other. Accordingly, each beam basically provides the same resolution as the beam of a conventional charged particle beam device.
