    Abstract: A lithographic apparatus is disclosed. The lithographic apparatus comprises a substrate table configured to support a substrate; actuators configurable to move the substrate table in a plane substantially parallel to the surface of the substrate; a projection system configured to pattern the substrate with fields aligned in a scanning exposure direction; a level sensor configured to sense a height of the substrate using a plurality of measurement spots; and a controller configured to control the actuators to generate strokes of relative movement between the substrate and the level sensor for mapping the height of the substrate, said strokes being at an angle of less than 20 degrees relative to the scanning exposure direction. Also disclosed is an associated method of mapping the height of a substrate.

    Abstract: A method for converting a vector-based representation of a desired device pattern for an exposure apparatus, a lithography or exposure apparatus, an apparatus and method to provide data to a programmable patterning device, and a device manufacturing method. In an embodiment, the method for converting outputs a rasterized representation of the desired dose pattern of radiation corresponding to the desired device pattern, wherein the vector-based representation comprises primitive data identifying one or more primitive patterns; and instance data identifying how at least a portion of the desired device pattern is formed from one or more instances of each identified primitive pattern, the method including forming a rasterized primitive of each primitive pattern identified in the primitive data, and forming the rasterized representation by storing each rasterized primitive in association with the instance data corresponding to that rasterized primitive.
