Abstract:
An electron beam exposure method of drawing a plurality of partial patterns on a plurality of element regions on a substrate with a plurality of electron beams, wherein each of the plurality of element regions is scanned with a corresponding one of the plurality of electron beams, thereby drawing a pattern constituted by the plurality of partial patterns on the substrate, said method comprising:a determination step of determining, for each of the plurality of element regions, an electron beam irradiation amount that is common for irradiation positions within a corresponding one of the plurality of element regions so as to reduce an influence of a proximity effect upon the element region when an associated region, including the element region and regions close to the element region, is irradiated with the electron beam; and a drawing step of drawing the partial patterns on the plurality of element regions on the substrate with the plurality of electron beams while controlling the plurality of electron beams to have the electron beam irradiation amounts determined in said determination step.
