摘要： A spectrometer objective is composed of a short focal length, asymmetrical objective lens comprising an integrated electrostatic opposing field spectrometer and a single-stage deflection system arranged within the magnetic lens. Since the deflection of primary electrons occurs within the spectrometer objective, the space for a two-state deflection system employed in conventional systems between a condenser lens and an objective lens can be eliminated. The extremely-short structural length of the electron beam measuring apparatus which is thereby obtainable, in turn, has a beneficial effect on the influence of the lateral Boersch effect on probe diameter, this influence increasing with the length of the electron-optical beam path.

摘要： A detector objective forms a component of an electron-optical column of a scanning electron microscope, the detector objective being composed of an asymmetrical magnetic lens, an electrostatic immersion lens generating a substantially rotationally symmetrical field, and an annular detector disposed immediately above the magnetic lens body. An electrode of the electrostatic immersion lens is formed as a truncated cone and is arranged in insulated fashion in an upper pole piece of the magnetic lens. The lower pole piece forms the second electrode of the immersion lens. The first and second electrodes are charged with potentials that establish an electrical field for decelerating the primary electrons, the electrical field overlying the focusing magnetic field.

摘要： 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. The improvement of the energy resolution is significant, in particular when the beam tube element is part of a high voltage beam tube.
