    Abstract: A lithographic apparatus includes a substrate support (2) that is constructed to support a substrate (6), and a projection system (4) that is configured to project a patterned radiation beam (5) onto a target portion of the substrate. The substrate support is arranged to move the substrate along a predetermined trajectory (7) of subsequently targeted target portions of the substrate. The substrate support includes a duct configuration (1) for providing thermal stabilization to the substrate. The duct configuration is arranged to duct thermally stabilizing media in the support, and to substantially duct the media away from a part of the substrate support that supports the target portion via parts of the substrate support that support previously targeted portions of the substrate, so as to keep subsequently targeted target portions thermally stable.

    Abstract: A lithographic projection apparatus comprising: a radiation system for providing a projection beam of radiation; a support structure for supporting patterning means, the patterning means serving to pattern the projection beam according to a desired pattern; a substrate holder (2) comprising a plurality of protrusions (10,11,12), the extremities thereof defining a substantially flat plane of support for supporting a substantially flat substrate, said substrate holder provided with means to provide a pressing force for pressing the substrate against the extremities of the protrusions; the protrusions (10) in an edge zone of the substrate holder arranged to provide a substantially flat overhanging of the substrate in relation to the pressing force of the pressing means; and a projection system for projecting the patterned beam onto a target portion of the substrate. The lithographic projection apparatus is characterized in that said protrusions (11,12) in an off-edge zone of the substrate holder are distributed so as to provide a substantial equal supporting area (13) for each protrusion of said plurality of protrusions, said supporting areas being defined by a Voronoi diagram distribution associated to the protrusions. The lithographic apparatus according to the invention offers a substrate holder with a reduced overlay and focus error.

    Abstract: An article support constructed to support an article for lithographic processing purposes is disclosed. The article support includes a channel configuration arranged to guide thermally stabilizing media in the article support to provide thermal stabilization to the article, wherein the channel configuration comprises an input channel structure and an output channel structure, the input and output channel structures arranged in a nested configuration and connected to each other by a fine grid structure provided at or near a surface of the article support. A lithographic apparatus and device manufacturing incorporating the article support is also disclosed.

    Abstract: A lithographic apparatus is disclosed that includes an article support constructed to support a first article, capable of imparting a radiation beam with a pattern in its cross-section to form a patterned radiation beam, in a beam path of the radiation beam or a second article to be placed in a beam path of the patterned radiation beam, the article support having a plurality of supporting protrusions on which the first article or the second article is disposed in use, wherein the plurality of supporting protrusions are constructed to define a support zone to provide a plane of support for the first article or the second article, so that when the first article or the second article is subjected to a thermal load the support zone allows at least a portion of the first article or the second article to expand or contract to reduce the build up of a mechanical stress in the first article or second article, respectively, while maintaining the first article or second article substantially fixed to the article support, and a position sensor configured to determine a position offset, in a direction lying in the plane of the support zone, of the first article or the second article over a period of time, and a projection system configured to project a patterned radiation beam onto a target portion of a second article.
