Abstract:
1. A lithography apparatus, comprising: a patterning device comprising an array of individually controllable elements configured to impart a pattern to a cross-section of a beam of radiation; a projection system configured to project the patterned beam of radiation onto a target portion of a substrate; a data processing pipeline configured to convert a first data representation of a requested dose pattern to a sequence of control data suitable for controlling respective individually controllable elements in the array of individually controllable elements to form the pattern in the beam using the patterning device, such that the requested dose pattern is formed on a substrate, the data processing pipeline comprising, wherein the calculation load controller is configured to control a size of each of the sub-regions according to at least one of a degree of pattern irregularity, a pattern entropy, and a compression ratio of the portion of the requested dose pattern corresponding to that sub-region.
