  • Patent number: 10269536
    Abstract: The objective of the present invention is to simultaneously achieve image observations at a high resolution using an electron microscope, and X-ray analysis at a high energy-resolution using a microcalorimeter. An X-ray detector is disposed at a position where the intensity of the magnetic field from an objective lens is weaker than the critical magnetic field of a material used in a thermal insulation shield for a superconducting transition-edge sensor or a microcalorimeter. In addition, an optical system for transmitting X-rays to the detector is inserted between a sample and the detector. Alternatively, a magnetic field shield for shielding the X-ray detector is used.

  • Patent number: 10269534
    Abstract: The present invention relates to adjustment of a mask position by driving an R-axis of an electron microscope in order to adjust the mask position with high accuracy while performing observation by the electron microscope without providing a heat generation source inside the electron microscope. The R-axis originally exists in a sample chamber of the electron microscope, which enables control with high accuracy. The R-axis driving of a sample stage can be substituted by raster rotation, therefore, the mask position can be adjusted with high accuracy while performing observation by the electron microscope according to the present invention.

  • Patent number: 10249474
    Abstract: The scanning charged particle beam microscope according to the present application is characterized in that, in acquiring an image of the FOV (field of view), interspaced beam irradiation points are set, and then, a deflector is controlled so that a charged particle beam scan is performed faster when the charged particle beam irradiates a position on the sample between each of the irradiation points than when the charged particle beam irradiates a position on the sample corresponding to each of the irradiation points (a position on the sample corresponding to each pixel detecting a signal). This allows the effects from a micro-domain electrification occurring within the FOV to be mitigated or controlled.
