Abstract:
1. A method of creating writing data for writing a pattern on a target workpiece by using a writing apparatus provided with a plurality of columns that emit charged particle beams, comprising: inputting information on distance between optical centers of the plurality of columns variably shaping charged particle beams and emitting the charged particle beams variably shaped to the target workpiece; inputting layout data and virtually dividing a writing region indicated by the layout data into a plurality of small regions, by a width of one integer-th of the distance indicated by the information on distance; converting, for each small region, the layout data to a format adaptable to the writing apparatus to create, for the each small region, the writing data whose writing region is divided into the small regions and which is used for at least one of the plurality of columns variably shaping charged particle beams and emitting the charged particle beams variably shaped to the target workpiece; and outputting the writing data.
