    Abstract: Disclosed herein is a lithographic apparatus comprising: a movable stage comprising a support structure configured to support a patterning device; a projection system configured to project a patterned radiation beam onto a target portion of a substrate; and a plate positioned between the movable stage and the projection system; wherein the plate comprises: a first surface that faces the movable stage; a second surface that faces the projection system; an opening through the plate such that the patterned radiation beam passes through the opening, wherein the opening has at least a first side and a second side that extend from the first surface to the second surface; one or more gas outlets in the first side of the opening and one or more gas outlets in the first surface of the plate, wherein the gas outlets are configured such that gas is supplied, via the gas outlets, to a region between the movable stage and the projection system; one or more gas inlets in the second side of the opening, wherein the gas inlets are configured such that gas is extracted from the region between the movable stage and the projection system via the gas inlets; and all of the one or more gas outlets in the first surface of the plate are positioned and configured such that, for each of the one or more gas outlets, a line that is both orthogonal to the first surface and intersects the gas outlet does not intersect the patterning device at any point during the entire range of movement of the patterning device. Advantageously, the overlay errors are lower than that achieved with known techniques.

    Abstract: A fluid handling system for wetting a region of a surface of a substrate irradiated by a radiation beam. The fluid handling system comprises a first device (112) configured to confine a first liquid to a first space (111) between at least a part of the first device and the surface of the substrate. The first device comprising an aperture (10) formed therein for the passage therethrough of the radiation beam (B) to irradiate the region by passing through the first liquid. The first device comprising at least one first liquid supply member (20, 23, 34) configured to provide the first liquid to the first space and at least one extraction member (32) configured to remove liquid from the first space. The fluid handling system further comprises a second device (200) comprising at least one second liquid supply member (201) configured to provide a second liquid to a second space (211) between at least a part of the second device and the surface of the substrate, wherein there is a gap (g) on the surface of the substrate between the second liquid and the first liquid. The fluid handling system is configured to provide the second liquid to the second space without removing any liquid from the second space to form a liquid layer over at least the region, and is configured to provide the first liquid and the second liquid on the surface of the substrate simultaneously.

    Abstract: A route for a substrate support that supports a substrate in an immersion lithographic apparatus is calculated to satisfy the following constraints: after the edge of the substrate first contacts the immersion space, the substrate remains in contact with the immersion space until all target portions are exposed; exposures of target portions are performed whilst the substrate moves in a scan direction; and all movements of the substrate between exposures are, in a plane parallel to its upper surface, either curved or only in one of the scan directions or transverse directions. In order to reduce exposure defects at the edges of the substrate it is avoided to expose the immersion liquid to the ouside of the substrate (W) to be exposed. The transfer routes (R51) are designed to overly the wafer surface.
