Abstract
In one embodiment, a drawing data creation method includes inputting correction-map-including drawing data having a correction map to a converter, the correction map including dose amount information for each mesh area obtained by dividing a drawing area on a target drawn by a charged particle beam drawing apparatus, the drawing area being divided in a mesh shape, converting dose amount information in a second mesh area adjacent to a first mesh area to a representation based on dose amount information in the first mesh area to compress data of the dose amount information in the second mesh area, and outputting compressed-correction-map-including drawing data having a compressed correction map to a controller, the compressed correction map including dose amount information in which data in each of the plurality of mesh areas has been compressed.
