Patent ID: 8748841

Claim:
A drawing apparatus configured to perform drawing on a substrate with a plurality of charged particle beams, the apparatus comprising: a first aperture array configured to split a diverging charged particle beam into a plurality of charged particle beams; a converging lens array configured to form a plurality of first crossovers of the plurality of charged particle beams from the first aperture array; a collimator lens having a principal plane where the plurality of first crossovers is to be formed; a correcting system configured to correct angles of a plurality of charged particle beams from the collimator lens, and to form a plurality of second crossovers; and an element in which a plurality of apertures respectively corresponding to the plurality of second crossovers is formed, wherein apertures in the first aperture array and converging lenses in the converging lens array are arranged such that an arrangement of the plurality of first crossovers on the principal plane is different from an arrangement of the plurality of apertures, and that the plurality of second crossovers is aligned with the plurality of apertures on the element.
