  • Publication number: 20230307206
    Abstract: A charged particle beam apparatus that forms a probe with a charged particle beam and scans a specimen with the probe to acquire a scanning image. The charged particle beam apparatus includes an optical system for scanning the specimen with the probe; a detector that detects a signal generated from the specimen through the scanning of the specimen with the probe; and a control unit that controls the optical system. The control unit performs correction processing of acquiring a reference image obtained by the scanning of the specimen with the probe, comparing the reference image to a criterion image to determine a drift amount, and correcting a displacement of an irradiation position with the probe on the specimen based on the drift amount; and processing of setting a frequency with which the correction processing is to be performed based on the drift amount.

  • Patent number: 11698336
    Abstract: An analysis method includes: obtaining n×m pieces of map data by repeating, m times, a map measurement in which n pieces of map data are obtained by scanning a specimen with a primary probe to detect electrons emitted from the specimen with an electron spectrometer, while measurement energy ranges of an analyzer are varied; and generating a spectral map in which a position on the specimen is associated with a spectrum based on the n×m pieces of map data, the measurement energy ranges of m times of the map measurement not overlapping each other.

  • Patent number: 9714850
    Abstract: An information processing device includes a storage section 50 that stores a history relating to the acquisition of measurement data, a history relating to an analysis position within an analyzer, and a history relating to a predetermined operation performed on a specimen using the analyzer as log information linked to time information, and a display control section 22 that performs a control process that displays these histories within a log display area on a display screen 40 in time series based on the log information, the display control section 22 performing a control process that displays a measurement result image generated based on the measurement data on the display screen, and, when an operation input that selects one measurement result image, performing a control process that displays a history that corresponds to the measurement data used to generate the selected measurement result image.
