摘要： An immersion lithography tool with a diverter element, positioned between the immersion element and the substrate, for altering the “footprint” or shape of the meniscus of the body of immersion liquid between the last optical element and an immersion element on one side, and the substrate on the other side when the substrate is moved. The apparatus includes a substrate holder to hold the substrate having an imaging surface and a projection optical system having a last optical element. The projection optical system projects an image onto a target imaging area on the substrate through the immersion liquid filled in a gap between the imaging surface of the substrate and the last optical element. An immersion element maintains the immersion fluid in the gap. The diverter element is positioned between the immersion element and the substrate. The diverter element alters the footprint shape of the meniscus of the body of immersion liquid, thereby preventing or reducing the amount of leakage from a space between the substrate and the immersion element.

摘要： An immersion lithography apparatus includes a projection system having a final optical element and a stage that is movable to a position below the projection system such that a gap exists between the final optical element and a surface of the stage. An immersion liquid fills the gap between the surface and the final optical element. A liquid confinement member maintains the immersion liquid in the gap. The immersion liquid has a meniscus where the liquid contacts ambient gas, the meniscus defining a footprint of an immersion area. A movable liquid diverter is positioned between the liquid confinement member and the stage. The movable liquid diverter moves relative to the liquid confinement member in a direction parallel to the surface of the stage, and includes an opening that surrounds the immersion area, the opening contacting or being slightly spaced from the immersion area when the stage is stationary.

摘要： A gas curtain type immersion lithography apparatus has a fluid removing porous region adjacent the gas inlet to prevent evaporative cooling. The apparatus includes a substrate holder which holds a substrate having an imaging surface and a projection optical system having a last optical element. The projection optical system projects an image onto a target imaging area on the substrate through an immersion fluid filled in a gap between the imaging surface of the substrate and the last optical element. An immersion element maintains the immersion fluid in the gap. Gas is provided through an inlet into the gap. A porous region is provided adjacent the gas inlet. Immersion fluid that collects near the gas inlet is removed by the porous region.

摘要： Apparatus, systems and methods remove liquid from a workpiece. A first station subjects a workpiece to processing that leaves a liquid on a surface of the workpiece. A second station is disposed at a location spaced apart from the first station. A porous member is disposed between the first and second stations. The porous member has a liquid-phyllic surface that faces the workpiece and is spaced from a surface of the workpiece by a gap. The porous member has a length in a direction perpendicular to a movement direction in which the workpiece moves from the first station to the second station, the length being at least as large as a dimension of the workpiece in the direction perpendicular to the movement direction.

摘要： 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.

摘要： A lithography apparatus includes a fluid confinement plate which can completely submerge the imaging surface of a substrate. A gap, filled with immersion fluid, is provided between the imaging surface of the substrate and the last optical element of a projection optical system. The fluid confinement plate, which is positioned within the gap between the last optical element and the substrate, is sufficiently sized so that the imaging surface is completely submerged in the immersion fluid. The fluid confinement plate includes a first surface facing the gap and opposing the imaging surface of the substrate. The first surface includes a droplet control element to control the formation of droplets forming on the first surface.
