    Abstract: An electron microscope is provided, which enables an observation with high resolution. The electron microscope is able to detect the deviation of an electron beam relative to the opening of a slit quantitatively, thereby shifting the electron beam accurately to the center of the opening of slit so as to execute energy selection. The electron microscope has an energy filter control unit for adjusting a relative position between an electron beam and a slit by shifting the position of electron beam based on a signal delivered by an energy filter electron beam detector. Also a method for controlling an energy filter is provided, which includes the steps of shifting the position of an electron beam, determining the position of electron beam and letting the electron beam pass through the center of an opening of the slit by controlling the position of slit or position of electron beam.

    Abstract: A scanning transmission electron microscope has an electron beam energy analyzer (energy filter) to observe electron beam energy loss spectra and element distribution images. This electron microscope further includes a deflection coil provided on the upstream side of a magnetic sector to correct for the electron beam path in a plane normal to the optical axis and make the electron beam incident to the energy filter, a deflection coil for correcting for the electron beam path in the energy axis direction of an energy dispersion surface formed by the magnetic sector, and a control unit for controlling the exciting conditions of the deflection coils.

    Abstract: An invention providing a scanning electron microscope composed of a monochromator capable of high resolution, monochromatizing the energy and reducing chromatic aberrations without significantly lowering the electrical current strength of the primary electron beam. A scanning electron microscope is installed with a pair of sectorial magnetic and electrical fields having opposite deflection directions to focus the electron beam and then limit the energy width by means of slits, and another pair of sectorial magnetic and electrical fields of the same shape is installed at a position forming a symmetrical mirror versus the surface containing the slits. This structure acts to cancel out energy dispersion at the object point and symmetrical mirror positions, and by spatially contracting the point-converged spot beam with a converging lens system, improves the image resolution of the scanning electron microscope.

    Abstract: An apparatus and method for providing a low energy, high current ion beam for ion implantation applications are disclosed. The apparatus includes a mass analysis magnet mounted in a passageway along the path of an ion beam, and a magnetic device adapted to provide a multi-cusped magnetic field in the passageway, which may include a plurality of magnets mounted along at least a portion of the passageway. The magnets may cooperatively interact to provide a multi-cusped magnetic field along at least a portion of the passageway. The multi-cusped magnetic field may be superimposed on the dipole field at a specified field strength in a region of the mass analyzer passageway for a given low energy ion beam. The invention thus provides enhancement of beam plasma within a mass analyzer dipole magnetic field for low energy ion beams without the introduction of externally generated plasma. The invention further includes a method of providing ion beam containment in a low energy ion implantation system, as well as an ion implantation system.

    Abstract: In instruments such as Wien filters, electrostatic and/or magnetic pole pieces must be mounted on and secured to a supporting structure with a very high degree of dimensional precision, usually by brazing. To that end, a fixture is provided for holding the parts to be assembled in precise relationship and to press the pole pieces into engagement with the supporting structure while the securing operation is being carried out. The pressing is accomplished by a gravity-produced force which is, therefore, independent of positional accuracies caused by very high temperatures, such as are encountered during brazing.
