    摘要: A lithographic apparatus comprises an array of individually controllable elements that modulate a beam of radiation, a compressed-pattern memory that stores a compressed representation of a requested dose pattern to be formed on a substrate by the modulated beam, and a dictionary decompressor that at least partially decompresses the compressed representation. The dictionary decompressor comprises an external dictionary memory, a first dictionary decoder that at least partially decompresses at least a part of the compressed representation by extracting, from the external dictionary memory, portions of pattern data corresponding to references to the external dictionary memory contained in the compressed representation, and a second dictionary decoder having an internal dictionary memory, the second dictionary decoder that at least partially decompresses at least a part of the compressed representation by extracting, from the internal dictionary memory, portions of pattern data corresponding to references to the internal dictionary memory contained in compressed representation.

    摘要: A system is provided that includes a device having an emissive portion, a memory, and a dictionary decompressor. The device having an emissive portion is configured to produce a patterned beam. The memory is configured to store a compressed representation of a requested dose pattern, comprising two groups of repeating pattern features, to be formed on a surface by the patterned beam. The dictionary decompressor at least partially decompresses the compressed representation. The dictionary decompressor comprises a first dictionary memory configured to store pattern data corresponding to a first group of the two groups of repeating pattern features and a second dictionary memory configured to store pattern data corresponding to a second group of the two groups of repeating pattern features. The repeating pattern features in the first group have one or more differing characteristics than the repeating pattern features in the second group. Related methods are also provided.

    摘要: A lithography apparatus including a projection system configured to project a beam of radiation as an array of sub-beams of radiation and an array of individually controllable elements configured to modulate the sub-beams of radiation to form a requested dose pattern on a substrate. The requested dose pattern is built up over time from an array of localized exposures in which at least neighboring localized exposures are imaged at substantially different times and in which each localized exposure is produced by one of the sub-beams of radiation. The lithography apparatus also includes a rasterizer device arranged to convert data defining the requested dose pattern to a sequence of data representing the requested dose at a corresponding sequence of points within the pattern, and also a data manipulation device arranged to receive the sequence of data and constitute a control signal suitable for controlling the array of individually controllable elements.

    摘要: A lithographic apparatus comprises an array of individually controllable elements and a data processing pipeline. The array of individually controllable elements modulates a beam of radiation. The data processing pipeline converts a first representation of a requested dose pattern to a sequence of control data suitable for controlling the array of individually controllable elements in order substantially to form the requested dose pattern on a substrate. The data processing pipeline comprises an offline pre-processing device and an online rasterizer. The offline pre-processing device converts the first representation of the requested dose pattern to an intermediate representation, which can be rasterized in a fewer number of operations than the first representation. The storage device stores the intermediate representation. The online rasterizer accesses the stored intermediate representation and produces therefrom a stream of bitmap data to be used to generate the sequence of control data substantially in real time.
