Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a lithographic apparatus which facilitates transfer of heat to components, from components, or between components.SOLUTION: A lithographic apparatus 100 includes a substrate table WT configured to hold a substrate WA, and a projection system PS configured to project a patterned radiation beam onto a target portion of the substrate WA. A surface of a component, such as a wall of the projection system PS, the substrate table WT, a mirror 28, a heat sink and an internal chamber wall, of the lithographic apparatus 100 that is in a vacuum environment in use is provided with a repeating structure configured to increase the effective thermal accommodation coefficient of the surface. |
