    Abstract: PROBLEM TO BE SOLVED: To solve the problem on a conventional aberration correction in association with an orbital correcting method in a charged-particle beam, and to provide a convergent optical system for a charged-particle beam at low cost and with high accuracy and high resolution. SOLUTION: A distribution is constituted to concentrate the electromagnetic field in the central direction of its beam orbital axis, and the beam orbit is formed in an obliquely incident manner to constitute a curved orbit by means of a lenticular function. Resultantly, a large nonlinear operation in the outside is negated in such a typically exemplified case as a spherical aberration. More specifically, an electric field is easily concentrated when voltage is applied to an electrode on the axis. Further, a beam incident axis and an imaging position can be achieved by operating a normal lens and a deflector. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a lens system with an aperture for an electron beam in an arbitrary length dimension, and forming aplanatic images.
    SOLUTION: A cylindrical lens is combined with a magnetic lens with which a quadrupole field can be produced. The lenses are arranged with little or no distance between them and their optical axes run parallel to one another. The quadrupole lens has a slot-shaped aperture which is oriented parallel to an opening of the cylindrical lens. The focusing plane of the quadrupole lens, which surrounds the optical axis, is oriented parallel to the longitudinal axes of the aperture and its defocusing plane perpendicular to the longitudinal axes. The refractive power of the cylindrical lens can be set at twice that of the quadrupole lens.

    Abstract: PROBLEM TO BE SOLVED: To effectively observe irregularity of the surface of a sample, by detecting secondary electrons from the sample mounted in a lens magnetic field with a plurality of secondary electron detectors.
    SOLUTION: An upper electrode 3a and a lower electrode 3b of a scanning electron beam device 10 are constructed in a single pole magnetic field type lens 4 so that a sample 5 is mounted in the lens magnetic field, where a negative voltage is applied to the sample 5 and the lower electrode 3b facing the sample 5, a zero or positive voltage is applied to the upper electrode, and this generates an electric field, to prevent the secondary electrons, which are emitted into an object lens magnetic field space on the side of an electron source 1 from the sample 5, from moving in a spiral. The secondary electrons are detected by split MCPs or a plurality of scintillator type secondary electron detectors which are mounted so as to pinch an optical axis line.
