20090316121 | LITHOGRAPHIC APPARATUS AND METHOD - A lithographic apparatus of the immersion type is disclosed. In the apparatus, a plurality of heating and/or cooling devices are provided in the vicinity of the final element of the projection system, e.g. in a barrier member of a liquid handling system. The heating and/or cooling devices can be used, for example, to control temperature gradients in the final element of the projection system to control aberrations therein. | 12-24-2009 |
20100066987 | LITHOGRAPHIC APPARATUS AND A METHOD OF OPERATING THE APPARATUS - A lithographic apparatus is disclosed that includes a projection system, and a liquid confinement structure configured to at least partly confine immersion liquid to an immersion space defined by the projection system, the liquid confinement structure and a substrate and/or substrate table. Measures are taken in the lithographic apparatus, for example, to reduce the effect of droplets on the final element of the projection system or to substantially avoid such droplet formation. | 03-18-2010 |
20100066988 | LITHOGRAPHIC APPARATUS AND METHOD OF GENERATING THE APPARATUS - A lithographic apparatus comprising a projection system, and a liquid confinement structure configured to at least partly confine immersion liquid to an immersion space defined by the projection system, the liquid confinement structure and a substrate and/or substrate table is disclosed wherein a humid gas space is defined between the projection system, the liquid confinement structure and immersion liquid in the immersion space, the humid gas space being configured to contain humid gas. | 03-18-2010 |
20100296067 | LITHOGRAPHIC APPARATUS AND METHOD OF OPERATING THE APPARATUS - A lithographic apparatus comprising a projection system, and a liquid confinement structure configured to at least partly confine immersion liquid to an immersion space defined by the projection system, the liquid confinement structure and a substrate and/or substrate table is disclosed wherein a measure is taken to reduce the effect of droplets and/or a liquid film on the last element of the projection system. | 11-25-2010 |
20110005603 | FLUID HANDLING STRUCTURE, LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A fluid handling structure configured to supply and confine immersion liquid to a space defined between a projection system and a facing surface facing the fluid handling structure is disclosed. The fluid handling structure includes a supply passage formed therein for the passage of fluid from outside the fluid handling structure to the space, and a thermal isolator positioned adjacent the supply passage at least partly to isolate fluid in the supply passage from a thermal load induced in the fluid handling structure. | 01-13-2011 |
20110007287 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - An immersion lithographic apparatus comprising a surface which is curved such that a surface-tension drainage force acts in a direction on a film of immersion liquid on the surface. | 01-13-2011 |
20110181849 | LITHOGRAPHIC APPARATUS AND A DEVICE MANUFACTURING METHOD - An immersion lithographic apparatus is provided having a substrate table including a drain configured to receive immersion fluid which leaks into a gap between an edge of a substrate on the substrate table and an edge of a recess in which the substrate is located. A thermal conditioning system is provided to thermally condition at least the portion of the recess supporting the substrate by directing one or more jets of fluid onto a reverse side of the section supporting the substrate. | 07-28-2011 |
20140098353 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A liquid confinement system for use in immersion lithography is disclosed in which the meniscus of liquid between the liquid confinement system and the substrate is pinned substantially in place by a meniscus pinning feature. The meniscus pinning feature comprises a plurality of discrete outlets arranged in a polygonal shape. | 04-10-2014 |
