Abstract:
In accordance with an embodiment, a charged particle beam apparatus includes an irradiating section, a detecting section, a range setting section, a scanning control section, a control section, and a sample position calibrating section. The range setting section sets a scanning range of a charged particle beam. The scanning control section scans the set scanning range with the charged particle beam. The control section relatively rotates the sample by each predetermined unit in association with an entering direction of the charged particle beam, detects peak values of the signal from the detecting section when the scanning range is scanned by each rotating angle with the charged particle beam, specifies the rotating angle corresponding to the maximum peak value among the peak values of the respective detected rotating angles, and specifies a reference position to observe the sample on the basis of the specified rotating angle.
Abstract:
In accordance with an embodiment, a method of adjusting quality of an image of patterns common in shape includes acquiring a first gray value and a first waveform within a reference image, acquiring a sample image, acquiring a second gray value and a second waveform from third and fourth regions within a sample image, respectively, and adjusting the brightness and contrast of the sample image. The first gray value is a standard for the brightness of the image from a first region within a reference image. The first and second waveforms represent a luminance profile of second and fourth regions including edges, respectively. The third and fourth regions correspond to the first and second regions. The brightness and contrast of the sample image are adjusted by matching the first gray value and the first waveform with the second gray value and the second waveform.
Abstract:
According to one embodiment, a processing device causes a display of a first object at a position separated from a fastening location of a screw. The first object is virtual and indicates the fastening location. The processing device associates first data and second data when a prescribed physical object contacts the first object and the first data is received from a tool turning the screw. The second data is related to the fastening location.
