Abstract: Apparatuses and techniques for suppressing a zeroth order portion of a configured radiation beam. In some embodiments, an extreme ultraviolet (EUV) lithographic apparatus for forming an image on a substrate by use of an EUV radiation beam that is configured by a patterning device comprising a pattern of reflective regions and partially reflective regions, wherein the partially reflective regions are configured to suppress and apply a phase shift to a portion of the EUV radiation beam, may include a projection system. The projection system may be configured to suppress a zeroth order portion of a configured EUV radiation beam, and direct an unsuppressed portion of a configured EUV radiation beam towards a substrate to form an image on the substrate.

Abstract: An immersion lithographic apparatus including: a liquid confinement structure configured to supply and confine immersion liquid to an immersion space between a final lens element of a projection system and a surface of the substrate and/or of a substrate table; and a passageway-former between the projection system and the liquid confinement structure, and a passageway between the passageway-former and an optically active part of the final lens element, the passageway being in liquid communication via an opening with the immersion space and extending radially outwardly, with respect to an optical axis of the projection system, at least to an edge of an exposed bottom surface of the final lens element and being constructed and configured such that in use it is filled with liquid from the immersion space by capillary action.

Abstract: An immersion lithographic apparatus includes a projection system. The projection system is configured to project a patterned radiation beam through an immersion liquid onto a target portion of a substrate. An external surface of the projection system includes a first surface. The first surface has a non-planar shape. An element is attached to the first surface and positioned so that at least a portion of the element contacts the immersion liquid in use. The element includes a closed loop of continuously integral material in a preformed state and conforms to the non-planar shape of the first surface.
