Abstract:
A charged particle beam device is provided which minimizes the beam irradiation amount while maintaining a high measurement success rate. The charged particle beam device includes a control device for controlling a scan deflector on the basis of selection of a predetermined number n of frames, wherein the control device controls the scan deflector so that a charged particle beam is selectively scanned on a portion on a sample corresponding to a pixel satisfying a predetermined condition or a region including the portion on the sample from an image obtained by scanning the charged particle beam for a number m of frames (m≥1), the number m of frames being smaller than the number n of frames.

Claim (Index 1):
A charged particle beam device comprising:\n a scanning deflector that performs scanning with a charged particle beam discharged from a charged particle source; a detector that detects a charged particle obtained based on the scanning with the charged particle beam; and a control device that adjusts an irradiation condition of the charged particle beam in at least two ways, wherein the control device measures or inspects a pattern formed on a sample, based on a signal obtained by scanning a first region on the sample with a first charged particle beam, wherein the control device scans a second region including the first region with a second charged particle beam whose dose amount is smaller than that of the first charged particle beam, specifies an edge portion of the pattern or a position of the pattern by comparing a luminance value or a contrast value of each pixel in an image, which is formed from a signal obtained by scanning with the second charged particle beam, with a first predetermined threshold, and determines the first region and a scanning direction of the first charged particle beam, based on the specified edge portion of the pattern or the specified position of the pattern, and wherein a difference between luminance values or contrast values of adjacent pixels is calculated and a pixel position of a background part is determined by comparing the difference with a second predetermined threshold.
