    摘要: An immersion lithography apparatus is disclosed in which liquid is supplied to a space between a projection system and a substrate, and a plate structure is provided to divide the space into two parts. The plate structure has an aperture to allow transmission of the projection beam, has through holes in it to reduce the damping effect of the presence of the plate and optionally has one or more inlets and outlets to provide various flows around the aperture in the plate. An embodiment of the invention may reduce the transportation of contaminants, stray light, temperature gradients, and/or the effect of bubbles on the imaging quality.

    摘要: A method of helping to prevent liquid reaching under a substrate is disclosed that includes introducing a gas at a bottom edge of the substrate so that a buffer is created at the edge of the substrate, helping to keep immersion liquid that is present at the top and edge of the substrate away from the bottom surface of the substrate.
