    摘要: A lithographic projection apparatus is disclosed. The apparatus includes a radiation system that provides a beam of radiation, and a support structure that supports a patterning structure. The patterning structure is configured to pattern the beam of radiation according to a desired pattern. The apparatus also includes a substrate support that supports a substrate, a projection system that projects the patterned beam onto a target portion of the substrate, a plurality of optical elements that form part of at least one of the radiation system, the patterning structure, and the projection system; and a cleaning device. The cleaning device includes at least one cleaning beam of radiation, and a gas. The cleaning device is configured to clean an individual optical element or a subset of the plurality of optical elements.
