Abstract:
1. A charged particle beam writing system comprising: a resizing data generation part configured to: calculate in a first direction, with a resizing data generation apparatus, a first dimension correction amount for correcting a dimension error caused by a loading effect, for a pattern to be written in which each small region of a plurality regions is made by virtually dividing a writing region of a target workpiece into meshes of a predetermined size, based on an area density of the each small region, the pattern to be written in the each small region having at least two dimensions in the first direction, wherein the at least two dimensions represent line widths of the pattern, to calculate, with said resizing data generation apparatus, second and third dimension correction amounts in the first direction for said at least two dimensions of the pattern to be written in the each small region, wherein the second and third dimension correction amounts in the first direction changing in accordance with a value of each of the at least two dimensions of the pattern to be written in the each small region, to correct, with said resizing data generation apparatus, the first dimension correction amount by using one of the second and third dimension correction amounts for each of the at least two dimensions of the pattern to be written in the each small region, one of the second and third dimension correction amounts being used for one of the at least two dimensions of the pattern to be written in the each small region and another one of the second and third dimension correction amounts being used for other one of the at least two dimensions of the pattern to be written in the each small region, wherein correcting the first dimension correction amount by using one of the second and third dimension correction amounts for one of the at least two dimensions of the pattern to be written in the each small region results in a first corrected first dimension correction amount, wherein correcting the first dimension correction amount by using said another one of the second and third dimension correction amounts for said another one of the at least two dimensions of the pattern to be written in the each small region results in a second corrected first dimension correction amount, to resize, with said resizing data generation apparatus, one of the at least two dimensions of the pattern to be written in the each small region by using the first corrected first dimension correction amount, to resize, with said resizing data generation apparatus, said another one of the at least two dimensions of the pattern to be written in the each small region by using the second corrected first dimension correction amount, and to output a result of the resizing of said one of the at least two dimensions of the pattern to be written in the each small region and the resizing of said another one of the at least two dimensions of the pattern to be written in the each small region; and a writing part configured to write a pattern resized by the resizing data generation part, on the target workpiece using a charged particle beam.
