    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 lithographic apparatus may include an optical element, such as an immersion fluid reservoir, which supported at least in part by a bearing, such as a gas bearing. To enable illumination by the lithographic apparatus of an edge of the substrate, a surrounding structure is provided that surrounds the substrate. A level parameter of the substrate, such as a thickness of the substrate, is measured by a sensor, such as a thickness sensor. By means of an actuator, the substrate table on which the substrate is or will be held is positioned with respect to the surrounding structure, such that a surface of the substrate would be on a substantially same level as a surface of the surrounding structure, thus enabling the optical element to transition from the surface of the substrate to the surface of the surrounding structure and vice versa.
