    摘要: An exemplary a charged particle beam apparatus converts an inspection position on a test sample (wafer coordinate system) to a setting position of an inspection mechanism (stage coordinate system (polar coordinate system)), a rotating arm and a rotating stage being rotated to be moved for the inspection position on the test sample. In this case, inspection devices are arranged over a locus that is drawn by the center of the rotating stage according to the rotation of the rotating arm. A function for calculating errors (e.g., center shift of the rotating stage) and compensating for the errors is provided, by which the precision of inspection is improved in a charged particle beam apparatus equipped with a biaxial rotating stage mechanism.

    摘要: The invention relates to a trajectory correction method for a charged particle beam, and provides a low-cost, high accuracy and high-resolution converging optical system for use with a charged particle beam to solve problems with conventional aberration correction systems. To this end, the present invention uses a configuration which forms electromagnetic field which is concentrated towards a center of a beam trajectory axis, causes oblique of the beam to make use of lens effects and bend the trajectory, and consequently, cancels out large external side non-linear effects such a spherical aberration of the electron lens. Specifically, the configuration generates an electric field concentration in a simple manner by providing electrodes above the axis and applying voltages to the electrodes. Further, the above configuration can be realized trough operations using lenses and deflectors with incident axes and image formation positions that are normal.

A charged particle detector for a bright-field image is provided below the above opening. By the deflecting coil below the sample, a charged particle beam for a bright-field image is configured to be synchronized with the scanning of a particle beam, and to be deflected in an opposite direction to the deflected direction of the particle beam. Thereby, a charged particles beam of a bright-field image passes through the opening of the charged particle detector for a dark-field image, and is detected by the charged particle detector for a bright-field image.

    摘要: The objective of the present invention is to provide a charged particle beam device such that a tip part can be effectually maintained in a clean state, while the frequency of valve body replacements is also reduced. To achieve the objective, a charged particle beam device is offered, comprising: a partition that is positioned between a charged particle source-side vacuum space and a specimen stage-side vacuum space, said partition further comprising an opening for a charged particle beam to pass through; a driver mechanism that moves a shutter member between a first location within the optical axis of the charged particle beam and a second location outside the optical axis of the charged particle beam; and a control device that controls the driver mechanism. The first location is a location wherein the shutter member is distanced from the partition, and the control device carries out a control that opens a valve between the specimen chamber and the exchange chamber when the shutter member is in a state of being located in the first location.

    摘要: As an image forming method including comparison between images for three-dimensional image construction or the like and an apparatus for forming such images, there are provided an image forming method and an electron microscope capable of obtaining with high accuracy or efficiency information required for comparison. In the image forming method, an image is formed on the basis of comparison between a plurality of images obtained by applying an electron beam to a specimen at different tilt angles. The method includes obtaining a first transmission image with the electron beam applied in a first direction and a second transmission image with the electron beam applied in a second direction, the second transmission image being formed within a region different from a peripheral blurred region resulting from tilting, and making a search in the first transmission image by using the second transmission image.
