A lithographic projection apparatus is disclosed in which the space between the final element of the projection system and the substrate is filled with a liquid. An edge seal member 17, 117 at least partly surrounds the substrate W or other object on the substrate table WT to prevent catastrophic liquid loss when edge portions of the substrate or are imaged or illuminated.
摘要:
In a lithographic projection apparatus a liquid supply system maintains liquid in a space between a final element of the projection system and the substrate of the lithographic projection apparatus. A sensor positioned on a substrate table which holds the substrate is adapted for being imaged when immersed in immersion liquid (i.e. under the same conditions as the substrate will be imaged). By ensuring that a primary outer surface of an absorption element of the sensor is formed of one or fewer metal types, long life of the sensor can be expected.

摘要:
In order to improve the productivity of a lithographic apparatus, a stage apparatus for holding two patterning devices is described. The patterning devices are arranged such that the distance (d) between the patterns in the scanning direction corresponds to the length of the pattern in the scanning direction. By doing so, an improved exposure sequence may be performed by exposing a first die (13) with a first pattern (11), skipping a second die adjacent to the first die, and exposing a third die (14) adjacent to the second die using a second pattern (10).
摘要:
In a lithographic projection apparatus a liquid supply system maintains liquid in a space between the final element of the projection system and the substrate of the lithographic projection apparatus. A shutter member (150) is provided to take the place of the substrate in containing the liquid (11) in the liquid supply system during substrate exchange.
摘要:
A lithographic apparatus comprising an illumination system configured to condition a radiation beam; a support constructed to support a patterning device, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table constructed to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate (W), and a sensor (20) at substrate level comprising a radiation-receiving element, a transmissive plate supporting said radiation-receiving element, and a radiation-detecting means, wherein said sensor at substrate level is arranged to avoid loss of radiation between said radiation-receiving element (18) and the final element (40) of said radiation-detecting means.
