Patent ID: 8878149

Claim:
A charged particle beam writing apparatus comprising: a storage unit configured to store writing data in which there are defined a plurality of figures which are in contact and resizing information indicating, with respect to each of the plurality of figures, a resizing status whether or not to perform resizing and a resizing direction used when performing resizing; a judgment determination unit configured to input the writing data and judge, with respect to each of the plurality of figures which are in contact, the resizing status whether or not to perform resizing and the resizing direction used when performing resizing, wherein the resizing direction includes an upper, a lower, a left, and a right side, each of the upper, the lower, the left, and the right sides being defined by bit data, the judgment determination unit judges not to perform resizing in a case that bit data values of each of the upper, the lower, the left, and the right sides are both one of zero and one, and the judgment determination unit judges by the bit values whether to perform resizing in a case that another one of zero and one is defined as one of the bit data values; a resize processing unit configured to resize, with respect to each of the plurality of figures, a dimension of a figure concerned in a judged resizing direction when it is judged to perform resizing; and a writing unit configured to write a pattern onto a target workpiece with using a resized figure and a charged particle beam.
