Abstract: An immersion lithographic apparatus includes a projection system, a first table with a first planar surface and a second table with a second planar surface, the first and second planar surfaces being substantially coplanar, a liquid confinement system configured to spatially confine an immersion liquid to a volume with a first surface area that is coplanar with the first and second planar surfaces, and is substantially smaller than a second surface area of the top surface of the substrate, and a swap bridge member attached to the first table, the swap bridge member having an upper surface that is substantially coplanar with the first and second planar surfaces, wherein the upper surface of the swap bridge member is configured to serve as part of the liquid confinement system and to deform when the swap bridge member collides with the second table and to remain attached to the first table
