Abstract
A multi-charged particle beam writing apparatus includes a beam forming mechanism to form multi-charged-particle-beams, a block region forming circuit to form plural block regions from an irradiation region of the multi-charged-particle-beams formed by combining plural sub-regions each surrounded by a beam, being different from each other, and plural other beams adjacent to the beam in the multi-charged-particle-beams, and a writing mechanism to perform, using the multi-charged-particle-beams, multiple writing such that irradiation of each block region of the plural block regions is at least performed by any one of writing processing of the multiple writing, and such that each writing processing of the multiple writing is performed to write a writing region of a target object in a manner of covering the writing region without overlapping by, using one of the plural block regions, irradiation of the one of the plural block regions.
