Abstract: A fluid handling structure for a lithographic apparatus, the structure having: an aperture for the passage therethrough of a beam; a first part; and a second part, wherein the first and/or second part define a surface for the extraction of immersion fluid, relative movement between the first and second parts is effective to change a position of fluid flow into or out of the surface relative to the aperture, and the first or second part has at least one through-hole for the fluid flow and the other of the first or second part has at least one opening for the fluid flow, the at least one through-hole and at least one opening being in fluid communication when aligned, the relative movement allowing alignment of the at least one opening with different ones of the through-hole to change the position of the fluid flow into or out of the surface.

Abstract: The invention relates to an electrostatic holder comprising: a body, and a clamping element attached to the body, said clamping element comprising an electrode for applying an attractive force between the clamping element and a first to be clamped object, wherein an outer edge of the body is configured to provide a gap between the outer edge of the body and the first to be clamped object, which gap is configured for outputting a fluid for reducing dust particles reaching the first to be clamped object or a second to be clamped object on an opposite side of the holder.

Abstract: A substrate holder, for a lithographic apparatus, having a main body, a plurality of support elements to support a substrate and a seal unit. The seal unit may include a first seal positioned outward of and surrounding the plurality of support elements. A position of a substrate contact region of an upper surface of the first seal may be arranged at a distance from the plurality of support elements sufficient enough such that during the loading/unloading of the substrate, a force applied to the first seal by the substrate is greater than a force applied to the plurality of support elements by the substrate. A profile of the contact region, in a cross section through the seal, may have a shape which is configured such that during the loading/unloading of the substrate, the substrate contacts the seal via at least two different points of the profile.
