Abstract: Apparatus and methods keep immersion liquid in a space adjacent to an optical assembly. An optical assembly projects an image onto a substrate supported adjacent to the optical assembly by a substrate table. An insertion member insertable into the space between the optical assembly and the substrate, the substrate table, or both, divides the immersion liquid into a first portion and a second portion, the first portion disposed between the optical assembly and the insertion member, and the second portion disposed between the insertion member and the substrate, the substrate table, or both. The insertion member keeps the optical assembly in contact with the first portion when the substrate is moved away from being disposed adjacent to the optical assembly.

Abstract: A method of displaying a user interface to harvest feedback information pertaining to transactions facilitated by a computerized transaction facility includes the display of multiple feedback windows, or other distinct areas, within a user interface displayed on a display device. Each feedback window includes transaction identifier information that identifies a respective transaction. Each feedback window also includes a feedback input that receives feedback information, pertaining to an associated transaction identified by the transaction information. The feedback input is displayed, within each feedback window, to indicate an association with the respective transaction information. Accordingly, feedback input for multiple transactions may conveniently be inputted through a single user interface.

Abstract: Immersion liquid is recovered in an immersion lithography apparatus. A confinement member includes first and second outlets, each of which recovers an immersion liquid from an immersion area including a gap between a projection system and an object. The second outlet is radially farther from the gap than the first outlet. A porous member covers the second outlet. The first outlet is not covered by any porous member. A first low pressure provided to the first outlet causes more than 50% of recovered immersion liquid to flow through the first outlet. A second low pressure provided to the second outlet maintains a pressure at a surface of the porous member below the porous member's bubble point. A porous member can be disposed on the substrate-holding table adjacent the substrate holding area. Immersion liquid overflowing from the substrate is collected by the porous member.

Abstract: An apparatus and method are disclosed for providing fluid for immersion lithography. Immersion fluid is injected into an inner cavity in a direction that is different than a direction in which the nozzle moves. The immersion fluid can also be injected at different rates into the inner cavity at different sides. A wafer substrate is then exposed by light through the immersion fluid.

Abstract: A lithographic projection apparatus projects a pattern from a patterning device onto a substrate using a projection system. The apparatus has a liquid supply system to supply a liquid to a space between the projection system and the substrate. The apparatus also has a fluid removal system including a chamber to hold liquid and having an open end adjacent to a volume in which fluid will be present. The open end removes, through a pressure differential across-the open end when liquid is present in the chamber, substantially only liquid from the volume when liquid in the volume is adjacent to the open end but not gas from the volume when gas in the volume is adjacent to the open end.

Abstract: A stage assembly (220A) includes a stage (206A) and a force provider (232A) that provides an acceleration/deceleration force on the stage (206A). The force provider (232A) includes a provider housing (238A) and a piston assembly (240A). The provider housing (238A) defines a piston chamber (344), and includes a first beam aperture (352F), a first cylinder aperture (350F) that is in fluid communication with a fluid at a first pressure and a spaced apart second cylinder aperture (350S) that is in fluid communication with a fluid at the first pressure. The piston assembly (340) includes a piston (356) positioned in the piston chamber (344), and a first beam (358F)) extending through the first beam aperture (352F). The first beam (358F)) is secured to the piston (356). The piston (356) moves along a piston path (462). At a second piston region (462S) of the piston path (462) the piston (356) is positioned between the cylinder apertures (350F)(350S).

Abstract: Immersion liquid is contained in the immersion area located between the last optical member of a projection system and a surface that is the subject of exposure by providing a liquid seal located adjacent to the immersion area. The liquid seal extends between the surface to be exposed and a seal-holding-surface located adjacent to the immersion area. The liquid seal is a seal-forming-liquid that is different from the immersion liquid and that is maintained in place between the surface to be exposed and the seal-holding-surface only by surface tension.

Abstract: Immersion fluid remaining on a portion of a substrate after that portion has passed an immersion nozzle is removed by moving the substrate relative to an immersion nozzle so that the portion of the substrate on which the immersion fluid remains is passed by the immersion nozzle again. A path is determined along which the substrate is to be moved to remove the remaining immersion fluid. The path can be determined based upon previous movements of the substrate, including factors such as the speed and/or length of the previous movements. Alternatively, portions of the substrate on which immersion fluid remains can be detected, and then the substrate can be moved so that the portion of the substrate on which the immersion fluid remains is passed by the immersion nozzle based on the results of the detection. Immersion fluid also can be removed from the stage surface located beyond the substrate.

Abstract: A apparatus and methods recover a fluid from an immersion area formed in a gap between a projection system and an object of exposure in an immersion lithography system. A porous member is disposed adjacent to the immersion area. A pressure control system provides a first low pressure to a first portion of the porous member to remove immersion fluid that escapes from the immersion area, and provides a second low pressure to a second portion of the porous member to remove immersion fluid that escapes from the immersion area. The second low pressure is different from the first low pressure.

Abstract: Systems and methods control the fluid flow and pressure to provide stable conditions for immersion lithography. A fluid is provided in a space between a lens and a substrate during the immersion lithography process. Fluid is supplied to the space and is recovered from the space through a porous member in fluidic communication with the space. Maintaining the pressure in the porous member under the bubble point of the porous member can eliminate noise created by mixing air with the fluid during fluid recovery. The method can include drawing the fluid from the space via a recovery flow line through a porous member, and maintaining a pressure of the fluid in the porous member below a bubble point of the porous member during drawing of the fluid from the space.
