Claim Text:
1. A drawing apparatus for performing drawing on a substrate with a charged particle beam, the apparatus comprising: a substrate stage configured to hold the substrate and be moved; a charged particle optical system having a function of irradiating a plurality of charged particle beams arrayed along a first axis, of individually blanking the plurality of charged particle beams, and of deflecting at least a portion of the plurality of charged particle beams to perform displacement of the at least a portion of the plurality of charged particle beams on the substrate; and a controller configured to control the drawing so as to perform multiple irradiation of a target portion on the substrate with at least a portion of the plurality of charged particle beams, wherein the controller is configured to control the drawing such that the substrate stage is moved in one direction along the first axis with respect to a plurality of shot regions formed on the substrate along the first axis, and the deflection for the displacement along the first axis is performed with drawing on each of the plurality of shot regions as a unit, and wherein the controller is configured to control the drawing such that, during drawing on a first shot region of the plurality of shot regions with at least a portion of the plurality of charged particle beams, charged particle beams, of the plurality of charged particle beams, located in a second shot region, of the plurality of shot regions, as the substrate stage is moved, are blanked, and after the drawing on the first shot region with the at least a portion of the plurality of charged particle beams is ended, the deflection for the displacement along the first axis is performed, and then drawing on the second shot region with at least a portion of the plurality of charged particle beams is started.
