Abstract:
A lithographic projection apparatus configured and arranged to image a pattern onto a substrate that is at least partially covered by a layer of radiation-sensitive material, said apparatus comprising:a radiation system configured and arranged to provide a projection beam of radiation; a support structure configured and arranged to support a patterning structure, the patterning structure serving to produce a desired pattern in the projection beam; a substrate table configured and arranged to hold the substrate; a projection system configured and arranged to project the patterned projection beam onto a target portion of the substrate; an image sensing device configured end arranged to measure a pattern in the patterned projection beam, said image sensing device including: a slab; at least one radiation-sensitive sensor arranged on a first side of the slab, said at least one sensor being an integral part of said slab and being sensitive to the radiation of the projection beam; and a film of a material that is non-transparent to the radiation of the projection beam, said film being provided on the first side of the slab over said at least one sensor and having a patterned segment above each sensor configured and arranged to selectively pass radiation of the projection beam to said sensor; and an intermediate plate made from a material having a thermal expansion coefficient below approximately 12Ã—10âˆ’6Kâˆ’1, wherein said slab is mounted with a surface opposite to the first side facing a slab-bearing surface of the intermediate plate.
