Abstract:
A method of operating a lithographic apparatus is disclosed. The method includes moving a substrate table supporting a substrate relative to a projection system and adjusting the scanning speed between the substrate table and the projection system during imaging of a target within a predefined area at or near an edge of the substrate, or adjusting the stepping speed between adjacent target positions in a predefined area at or near the edge of the substrate, or both. The adjusting the scanning and/or stepping speed may comprise lowering the speed. The projection system is configured to project a patterned beam of radiation on to a target portion of the substrate.
