Abstract:
PURPOSE: A lithography apparatus, a method for controlling the same, and a method for manufacturing a device using the same are provided to reduce the generation risk of imaging defects by supplying immersing liquid into a space between a projection system and an opposite surface. CONSTITUTION: Patterned radiation beam directs toward a substrate through a projection system. The substrate is supported by a table. A liquid handling system supplies immersing liquid into a space between the projection system and an opposite surface. The structure of an opening(70) affects the influence of a liquid handling structure(12) in which the liquid is contained. A controller controls the operation of the table with respect to the liquid handling system.
Abstract:
A fluid handling structure is disclosed which is designed for all wet immersion lithography. The fluid handling structure has a first opening to provide fluid to a space between a final element of a projection system and a substrate and/or substrate table, a barrier to resist the flow of liquid out of the space between the fluid handling structure and the substrate, and a second opening, which opens into an area radially outwardly of the space, to provide a flow of fluid from the fluid handling structure onto a top surface of the substrate and/or substrate table radially outwardly of the space. A controller may be provided such that flow of fluid towards a center of the substrate table is greater than the flow of fluid in a direction away from the center of the substrate table. [Figure 6]
Abstract:
A fluid handling structure is disclosed in which measures are taken to increase the speed at which meniscus breakdown occurs. Measures include the shape of a plurality of fluid extraction openings and the shape and density of a plurality of fluid supply openings in the fluid handling structure.
Abstract:
An immersion lithographic apparatus is described in which a liquid removal device is arranged to remove liquid from the substrate, e.g. during exposures, through a plurality of elongate slots arranged along a line and angled to that line. The liquid removal device may act as a meniscus pinning device in an immersion hood or may be used in a drying device to remove a droplet from the substrate.
