    Abstract: PROBLEM TO BE SOLVED: To solve such a problem that when acquiring an image of high magnification only in an arbitrary direction, in order to prevent shrinkage reduction by dispersing dose of fine pattern, deflection aberration due to deflection in the other direction in the plane coordinate axes is actualized.SOLUTION: Images of different vertical and horizontal pixel sizes are acquired by changing a plurality of combination conditions of the intensity ratio and rotation angle of a deflector. The intensity ratio and rotation angle are determined based on the variation of the image in the direction of larger pixel size. Deflection aberration can be reduced when performing measurement in the X direction with high accuracy, while extending the field of view in the Y direction.

    Abstract: PROBLEM TO BE SOLVED: To provide a particle optical device with magnetic means, which overcomes a fault of a well-known device, reduces and/or stabilizes heat generation in a coil and reduces heat transfer from the coil to a polar plate. SOLUTION: In the particle optical device which is magnetic means having a particle source for generating at least one charged particle beam and two polar plates, the polar plates are disposed mutually spaced apart so that a charged particle passes through the polar plates at the time of operation, a groove is provided on the polar plates and a coil wire is arranged in the groove. When viewed from a cross section relative to an extending direction of the groove, the groove has a width in a surface area of the polar plate narrower than that in an area spaced apart from the surface.

    Abstract: PROBLEM TO BE SOLVED: To measure and to correct with high accurately the geometric strain in an optional magnification, in a charged particle beam microscopic device. SOLUTION: A geometric strain in the first magnification is measured as an absolute strain, based on a standard sample having a periodic structure. A fine structure sample is photographed in the first magnification, with which the geometric strain is measured and in a second magnification with which the geometric strain is not measured. An expanded/contracted image, determined by expanding/contracting in an isotropic way the image in the first magnification up to the image in the second magnification is generated. Geometric strain in the second magnification is measured as relative strain, based on the expanded/contracted image. An absolute strain in the second magnification is determined, from the absolute strain in the first magnification and the relative strain in the second magnification. Thereafter, relative strain measurement is repeated, by replacing the second magnification with the first magnification, to thereby measure and correct the geometric strains at an arbitrary magnification.
