Abstract:
In a charged-particle multi-beam writing method a desired pattern is written on a target using a beam of energetic electrically charged particles, by imaging apertures of a pattern definition device onto the target, as a pattern image which is moved over the target. Thus, exposure stripes are formed which cover the region to be exposed in sequential exposures, and the exposure stripes are mutually overlapping, such that each area of said region is exposed by at least two different areas of the pattern image at different transversal offsets (Y 1 ). For each pixel, a corrected dose amount is calculated by dividing the value of the nominal dose amount by a correction factor (q), wherein the same correction factor (q) is used with pixels located at positions which differ only by said transversal offsets (Y 1 ) of overlapping stripes.

Claim (Index 11):
A pattern definition device comprising:\n a plurality of apertures transparent to a source of radiation, a data processing unit having at least one input terminal and in communication with the plurality of apertures transparent to a source of radiation wherein the data processing unit is configured to receive a set of instructions defining a desired pattern image to be exposed on a target area, wherein at least a portion of the plurality of apertures correspond to a plurality of pattern image pixels on the target area and the at least a portion of the plurality of apertures are configured to expose the pattern image pixels to a respective dose amount in accordance with the desired pattern image, and wherein the data processing is further configured to calculate a correction dose needed for each of the pattern image pixels to correct for a pattern beam overlap by dividing a value of the nominal dose amount by a correction factor dose, and wherein the data processing unit is further configured to communicate the correction dose to the plurality of apertures.
