The present invention provides numerous advantages such as a precision of displacement analysis of a fraction of pixel to thereby allow to improve the precision of focal analysis, or reduced number of pixels required to achieve the same precision, evaluation of reliability of the analysis by using the δ peak intensity, influence of varying background reduced by using a phase variance component. The improved performance by the present invention allows any operator skilled or not to achieve a best focusing.

    摘要: An autoadjusting electron microscope in which an image processor derives a third image constituting an analysis image from first and second images of a specimen by Fourier-transforming the first and second images to produce Fourier-transformed first and second images, computing a phase variant image from the Fourier-transformed first and second images, and Fourier-transforming or inverse Fourier-transforming the phase variant image to obtain the third image. A computer determines an amount of displacement between the first image and the second image based on a peak appearing in the third image. An identifier determines whether a consistency between the first image and the second image is within a predetermined range based on a magnitude of the peak appearing in the third image. A transformer transforms results obtained by the computer and the identifier into an amount of defocus of an electron lens relative to the specimen.

    摘要: An electric charged particle beam microscope measures a geometric distortion at an arbitrary magnification with high precision, and corrects the geometric distortion. A geometric distortion at a first magnification is measured as an absolute distortion based on a standard specimen having a cyclic structure. A microscopic structure specimen is photographed at a geometric distortion measured first magnification and at a geometric distortion unmeasured second magnification. The image at the first magnification is equally transformed to the second magnification to generate a scaled image. The geometric distortion at the second magnification is measured as a relative distortion based on the scaled image. The absolute distortion at the second magnification is obtained on the basis of the absolute distortion at the first magnification and the relative distortion at the second magnification. Subsequently, the second magnification is replaced with the first magnification, and the relative distortion measurement is repeated.

    摘要: Magnification errors are reduced in the required range of magnification in electric charged particle beam application apparatuses and critical dimension measurement instruments. To achieve this, a first image, whose magnification for the specimen is actually measured, is recorded, a second image, whose magnification for the specimen is unknown, is recorded, and the magnification of the second image for the first image is analyzed by using image analysis. Thereby, the magnification of the second image for the specimen is actually measured. Then, magnification is actually measured in the whole range of magnification by repeating the magnification analysis described above by taking the second image as the first image. Actually measuring the magnification of images for the specimen in the whole range of magnification and calibrating the same permits a reduction of magnification errors by a digit.

    摘要: A scanning transmission electron microscope which enhances correction accuracy of a de-scanning coil for canceling a transmitted-electron-beam position change on an electron detector. Here, this transmitted-electron-beam position change appears in accompaniment with a primary-electron-beam position change on a specimen caused by a scanning coil. First, control over the scanning coil is digitized. Moreover, while being synchronized with a digital control signal resulting from this digitization, values in a de-scanning table registered in a FM(2) are outputted to the de-scanning coil. Here, the de-scanning table is created as follows: Diffraction images before and after activating the scanning coil and the de-scanning coil are photographed using a camera. Then, based on a result acquired by analyzing a resultant displacement quantity of the diffraction images by the image processing, the de-scanning table is created.

    摘要: An electron microscope for simultaneously adjusting the tilt, rotation and temperature of the specimen, and rapidly heating a desired localized section of the specimen. Specimen holders support the specimen on one side, and contain a space on the other side. A laser beam mechanism for heating the vicinity of the specimen irradiates a focused laser beam onto the specimen from this space. The output from a light position sensor installed in the specimen holders is utilized to adjust the irradiation position of the focused laser beam by controlling a fine motion mechanism for inputting light into the vicinity of the specimen stand.
