摘要:
A lithographic projection apparatus includes a radiation system configured to form a beam of radiation from radiation emitted by a radiation source, as well as a support configured to hold a patterning device, which when irradiated by the beam of radiation provides the beam of radiation with a pattern. A substrate table is configured to hold a substrate, and a projection system is configured to image an irradiated portion of the patterning device onto a target portion of the substrate. The radiation system further includes an aperture at a distance from the optical axis, a reflector which is placed behind the aperture when seen from the source and a structure placed in a low radiation intensive region behind the aperture.
