    摘要: A system for cleaning a limited area of a top surface of a substrate table or an object positioned on a top surface of a substrate table is disclosed. The optical system used during normal imaging is adjusted to limit the cross-sectional area of a radiation beam to form a cleaning radiation beam which impinges on the limited area.
