Patent ID: 8829461

Claim:
A drawing apparatus which irradiates a plurality of charged particle beams on an object and thereby performs drawing a pattern on the object with the plurality of charged particle beams, the apparatus comprising: a plurality of blankers configured to individually blank the plurality of charged particle beams to individually adjust intensities of the plurality of charged particle beams irradiated on the object; a deflector configured to collectively deflect the plurality of charged particle beams to collectively change positions, irradiated with the plurality of charged particle beams, on the object; and a controller configured to control the plurality of blankers and the deflector, wherein the controller is configured to respectively obtain positions irradiated with the plurality of charged particle beams deflected by the controlled deflector, to generate control data based on the positions irradiated with the plurality of charged particle beams deflected by the deflector, and to individually control the plurality of blankers based on the control data so as to individually adjust the intensities of the plurality of charged particle beams irradiated on the object.
