Patent ID: 8796650

Claim:
A charged particle beam drawing method, comprising: drawing patterns corresponding to figures included in a drawing data inputted to a charged particle beam drawing apparatus, on a workpiece mounted on a movable stage by a charged particle beam passed through an opening of a first forming aperture member and an opening of a second forming aperture member; and moving the figures in the drawing data, on the basis of positions in the opening of the second forming aperture member so that a position difference of the charged particle beam is cancelled, where the charged particle beam for drawing the patterns corresponding to the figures is passed through, wherein a figure of the figures in the drawing data is moved by a position difference between a position in the opening of the second forming aperture member where a charged particle beam which is not deflected by a beam size changing deflector passes and a position in the opening of the second forming aperture member where a charged particle beam to form a pattern corresponding to the figure passes.
