    摘要: A charged particle beam apparatus capable of automatically measuring an image magnification error of an apparatus and capable of automatically calibrating the image magnification in high precision is provided. To this end, while an image processing operation of either an auto-correlation function or an FFT transformation is employed with respect to a scanning image of a reference material having a periodic structure, the averaged pitch dimension of which is known, averaged periodic information owned by the scanning image is detected so as to measure an image magnification error of the apparatus. Also, the information as to the acquired image magnification error is fed back to an image magnification control means of the apparatus so as to automatically execute a calibration as to the image magnification in high precision.

    摘要: A charged particle beam apparatus facilitating adjusting the beam center axis of a charged particle beam in a case where optical conditions are modified or in a case where the beam center axis of the charged particle beam is moved due to state variation of the apparatus. When the beam center axis of a primary charged particle beam is adjusted with a deflector (aligner), a processing step (1) for measuring the sensitivity of the aligner and a processing step (2) for detecting the deviation between the center of the primary charged particle beam and the center of the objective aperture are provided. The charged particle beam apparatus has means for determining the aligner set values, using the aligner sensitivity measured in the processing step (1) and the amount of deviation detected in the processing step (2), such that the primary charged particle beam passes through the center of the objective aperture and controlling the aligner using the aligner set values.

    摘要: Image evaluation method capable of objectively evaluating the image resolution of a microscope image. An image resolution method is characterized in that resolution in partial regions of an image is obtained over an entire area of the image or a portion of the image, averaging is performed over the entire area of the image or the portion of the image, and the averaged value is established as the resolution evaluation value of the entire area of the image or the portion of the image. This method eliminates the subjective impressions of the evaluator from evaluation of microscope image resolution, so image resolution evaluation values of high accuracy and good repeatability can be obtained.
