摘要:
An immersion lithographic apparatus is described with a drain configured to remove liquid from a gap between an edge of the substrate and the substrate table on which the substrate is supported. The drain is provided with a means to provide liquid to the drain irrespective of the position of the substrate table and/or a means to saturate gas within the drain. Those measures reduce the variations in heat load due to evaporation of liquid in the drain.

摘要:
A component of an immersion system of a lithographic apparatus is disclosed having a superhydrophobic surface which in use is not exposed to DUV radiation. Also, there is disclosed a surface of a lithographic apparatus which may come into contact with immersion liquid and is a threshold distance from a surface exposed in use to the projection beam has a superhydrophobic property.
摘要:
A method of helping to prevent liquid reaching under a substrate is disclosed that includes introducing a gas at a bottom edge of the substrate so that a buffer is created at the edge of the substrate, helping to keep immersion liquid that is present at the top and edge of the substrate away from the bottom surface of the substrate.
摘要:
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.
摘要:
An article support is constructed to support an article. The article support includes a back fill structure constructed to supply and extract a thermal buffering fluid to and from the article support. The back fill structure is connected to an extraction duct that is constructed and arranged to extract at least a gas phase of the thermal buffering fluid from the back fill structure. The back fill structure is connected to a supply duct, constructed and arranged to supply a liquid phase of the thermal buffering fluid to the back fill structure. The back fill structure is arranged to have the thermal buffering fluid brought in a combined liquid and gas phase to thermally connect with the article.
摘要:
A immersion lithographic apparatus is disclosed in which one or more liquid diverters are positioned in a space surrounded by a liquid confinement structure. A function of the liquid diverter(s) is to hinder the formation of one or more recirculation zones of immersion liquid which may lead to variations in refractive index of the immersion liquid in the space and thereby imaging errors.
摘要:
The invention relates to a lithographic apparatus arranged to transfer a pattern from a patterning device onto a substrate, including a cooling system to cool a part of the lithographic apparatus, the cooling system including a droplet ejector to form droplets and fire the droplets towards a cooling surface of the part of the lithographic apparatus to cool the part by evaporation of the droplets.
