Abstract:
A lithographic system has a lithographic apparatus, an inspection system and a controller. The lithographic apparatus includes a projection system configured to project a radiation beam onto a layer of material on or above a substrate. The inspection system is configured to inspect a pattern formed on the substrate. The pattern is formed on the substrate by application of the radiation beam. The controller is configured to control the lithographic apparatus to form a pattern based on data from an inspection by the inspection system of a previously exposed pattern.
Abstract:
The invention relates to intensity values for a plurality of beams used to irradiate a plurality of locations on a target are determined with reference to the position and/or rotation of the locations. Also provided is an associated lithographic or exposure apparatus, an associated device manufacturing method and an associated computer program.
Abstract:
A lithographic apparatus having a programmable patterning device and a projection system. The programmable patterning device is configured to provide a plurality of radiation beams. The projection system has a lens group array configured to project the plurality of radiation beams onto a substrate. The projection system further includes a focus adjuster in an optical path corresponding to a lens group of the lens group array. The focus adjuster has an optical element having substantially zero optical power.
Abstract:
An aspect of the present invention includes a method for patterning a workpiece covered at least partly with a layer sensitive to electromagnetic radiation, comprising the actions of, providing a data representation of at least one image to be imaged onto a plurality of locations of said workpiece, fracturing said data representation into a plurality of field stripes, repeating the actions of rasterizing a first field stripe of said data representation, modulating a modulator according to said rasterized field stripe, imaging said first field stripe onto a plurality of locations of said workpiece, rasterizing a second field stripe of said data representation while imaging said first field stripe onto said plurality of locations of said workpiece, terminating the repetition when a predetermined amount of said image is imaged onto said plurality of locations of said workpiece. Other aspects of the present invention are reflected in the detailed description, figures and claims.
