    摘要: A cleaning apparatus to clean a substrate or component of an immersion lithographic apparatus is disclosed. The cleaning apparatus may comprise a plasma radical source, a conduit and a radical confinement system. The plasma radical source may provide a flow of radicals. The conduit may supply radicals from the plasma radical source to the surface to be cleaned. The radical confinement system may direct the radicals to clean a localized portion of the surface. The cleaning apparatus may comprise a rotator and may be configured to clean a substrate edge. An immersion lithographic apparatus comprising the cleaning apparatus to clean a surface is also disclosed. The immersion lithographic apparatus may comprise a substrate table to support a substrate and a fluid confinement structure to at least partly confine immersion fluid between a projection system and a substrate table and/or substrate.
