摘要： A charged particle beam drawing apparatus for drawing patterns corresponding to figures in a drawing data, has a portion for dividing a drawing area on the workpiece into block frames, a portion for combining at least a first block frame and a second block frame into a virtual block frame, and a portion for transferring a data of the virtual block frame from an input data dividing module to a common memory of a first converter and a second converter. The first converter converts a data of a first figure included in the first block frame into a first drawing apparatus internal format data. The second converter converts a data of a second figure included in the second block frame into a second drawing apparatus internal format data. The first figure and the second figure are included in a cell extending over the first block frame and the second block frame.
