Abstract:
The objective of the present invention is to provide a charged particle beam device wherein scanning is performed through a scanning pattern that may suppress the influence from charge accumulation without having to perform blanking. In order to achieve this objective, a charged particle beam device is proposed wherein a first scan line is scanned by deflecting a charged particle beam in a first direction. The charged particle beam is deflected in a manner where the ending point of the first scan line is connected to the scan starting point of a second scan line which is arranged to be parallel to the first scan line so as to draw a scanning trajectory, thereby modifying the scan line position. The second scan line is scanned by scanning the charged particle beam from the scan starting point of the second scan line toward a second direction that is opposite to the first direction. After scanning the second scan line, the charged particle beam device scans the interior of a first frame by repeating the scan line position modification and the scanning of the charged particle beam toward the opposite direction. After scanning the first frame, the charged particle beam device starts the scanning of a second frame with the scan ending point contained within the first frame serving as the scan starting point.

Claim (Index 7):
The charged particle beam device according to  claim 6 ,\n wherein the control device controls the scanning deflector to scan an area within a fourth frame in such a manner that a first scan line of the fourth frame is scanned through deflection of the charged particle beam to the third direction from a scan ending point included in the third frame, a second scan line of the fourth frame is scanned by changing a scan line position through deflection of the charged particle beam such that a scanning trajectory which connects an ending point of the first scan line of the fourth frame and a scan starting point of the second scan line of the fourth frame located in parallel with the first scan line of the fourth frame is drawn and performing the scanning with the charged particle beam toward the fourth direction from the scan starting point of the second scan line of the fourth frame, and the changing of the scan line position and the scanning with the charged particle beam toward the opposite direction are repeatedly after the second scan line of the fourth frame is scanned.
