| 20080259295 | Lithographic apparatus and device manufacturing method - An immersion lithographic apparatus has adaptations to prevent or reduce bubble formation in one or more gaps in the substrate table by preventing bubbles escaping from the gap into the beam path and/or extracting bubbles that may form in the gap. | 10-23-2008 |
| 20090073408 | Lithographic apparatus and device manufacturing method - Lithographic Apparatus and Device Manufacturing Method A lithographic projection apparatus is disclosed in which measures are taken to prevent or reduce the presence of bubbles in liquid through which the projection beam radiates. This may be done, for example, by ensuring that a gap between a substrate and a substrate table is filled with immersion liquid or by causing a localized flow radially outwardly from the optical axis in the vicinity of the edge of the substrate. | 03-19-2009 |
| 20100044593 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - In an immersion lithographic apparatus, bubble formation in immersion liquid is reduced or prevented by reducing a gap size or area on a substrate table and/or covering the gap. | 02-25-2010 |
| 20100321650 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A lithographic apparatus is described having a liquid supply system configured to at least partly fill a space between a projection system of the lithographic apparatus and a substrate with liquid, a barrier member arranged to substantially contain the liquid within the space, and one or more elements to control and/or compensate for evaporation of liquid from the substrate. | 12-23-2010 |
| 20100321653 | LITHOGRAPHIC APPARATUS - A barrier member is provided for use in immersion lithography. The barrier member includes an extractor assembly on a bottom surface configured to face the substrate. The extractor assembly includes a plate configured to split the space between a liquid removal device and the substrate in two such that a meniscus is formed in an upper channel between the liquid removal device and the plate and below the plate between the plate and the substrate. | 12-23-2010 |
| 20110090474 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - In an immersion lithographic apparatus, bubble formation in immersion liquid is reduced or prevented by reducing a gap size or area on a substrate table and/or covering the gap. | 04-21-2011 |
| 20110183257 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - In an immersion lithographic apparatus, bubble formation in immersion liquid is reduced or prevented by reducing a gap size or area on a substrate table and/or covering the gap. | 07-28-2011 |
| 20110188015 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A lithographic projection apparatus is disclosed in which measures are taken to prevent or reduce the presence of bubbles in liquid through which the projection beam radiates. This may be done, for example, by ensuring that a gap between a substrate and a substrate table is filled with immersion liquid or by causing a localized flow radially outwardly from the optical axis in the vicinity of the edge of the substrate. | 08-04-2011 |
