Zusammenfassung:In a method of scanning a charged particle beam which can position the scan position to a proper location inside a deflectable range of the scan position of charged particle beam, the scan position of charged particle beam is deflected to a plurality of target objects inside a scan position deflectable region and on the basis of a shift of a target object at a scan location after deflection, the deflection amount at the scan location is corrected.
