摘要： The present invention provides an electrode assembly comprising two or more electrodes arranged around a primary axis forming a non-cylindrical channel space. General electronic apparatus/device, particularly apparatus of charged-particle beam such as electron microscope, may use the electrode assembly to create an optimized pattern of electrical field within non-cylindrical channel space. When the electrode assembly is used as a beam deflector in a magnetic objective lens, the electrical field within the central channel space can be co-optimized with the magnetic field for reducing aberration(s) such as distortion, field curvature, astigmatism, and chromatic aberration, after the beam passes through the central channel space.

摘要： The present invention provides an apparatus of charged-particle beam such as an electron microscope including a specimen table that can slide on a planar surface around the lower pole piece of the objective lens. The specimen table is confined in a specimen stage having one elastic protrusion and one or more elastic force receiving parts (e.g three permanent protrusions) that contact and press the table. When the specimen is under microscopic examination, disturbing vibration cannot generate a force sufficient to overcome the limiting friction between the specimen table and the planar surface of the objective lens. The invention exhibits numerous technical merits such as minimal or zero vibration noise, and improved image quality, among others.

摘要： Provided is a microtomic system and process for the preparation of sections for microscope examination. A cutting edge in the system can cut through a sample block and produce a section one end of which remains attached to the cutting edge. A voltage generator can generate a voltage and apply the voltage between the cutting edge and a section receiver such as a semiconductor chip grid. Through electrostatic force caused by the voltage, another end of the section can anchor to the section receiver. The section is then spread on the receiver. The system is automatable, highly efficient, and does not need liquid to float sample sections, and can therefore maintain the integration of the sample sections.
