Abstract:
In one embodiment, a charged particle beam writing apparatus includes a storage unit storing a polynomial and a correction map for correcting deviations of writing positions, a correction processing unit correcting pattern positions in a writing area of a writing target substrate by using the polynomial and correcting the pattern positions in a specific region included in the writing area by using the correction map, and a writing unit writing patterns on a substrate by using a charged particle beam in accordance with the pattern positions corrected by the correction processing unit.

Claim (Index 7):
A charged particle beam writing method comprising:\n writing a plurality of test patterns over a writing area of a first substrate through a writing unit of a charged particle beam writing apparatus; measuring a writing position of each of the plurality of test patterns to obtain a positional deviation from design coordinates of each test pattern; dividing the writing area into a specific region and a nonspecific region; calculating an approximate polynomial by fitting positional deviations of the test patterns within the nonspecific region to a coordinate system of the apparatus; generating a correction map for measurements of the writing positions of the test patterns within the specific region, the correction map being used to correct positional deviations to be partially corrected using the approximate polynomial; reading write data, in which pattern data concerning a plurality of figure patterns is defined, from a storage device; correcting positions of the plurality of figure patterns using the approximate polynomial; correcting the positions of the figure patterns within the specific region using the correction map; and writing, in accordance with the corrected positions, the figure patterns on a second substrate through the writing unit.
