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.
