摘要:
A lithographic apparatus and method, in an embodiment for immersion lithography, are disclosed with a single stage in which leveling and exposure are performed simultaneously.
摘要:
The lithographic apparatus includes a support structure configured to hold a patterning device. The patterning device is configured to pattern a beam of radiation according to a desired pattern. The lithographic apparatus further includes a substrate table configured to hold a substrate, a projection system configured to project the patterned beam onto a target portion of the substrate, a measurement system configured to measure a parameter of (a) the substrate table, or (b) the substrate, or (c) an image projected by the projection system, or (d) any combination of (a)-(c), and a liquid supply system configured to supply a liquid to a space between the substrate and the projection system. The lithographic apparatus also includes a shield disposed in a vicinity of a portion of the measurement system and configured to shield the portion of the measurement system from the liquid.
摘要:
In a lithographic projection apparatus, a liquid supply system maintains liquid in a space between a projection system of the lithographic projection apparatus and a substrate. A sensor positioned on a substrate table, which holds the substrate, is configured to be exposed to radiation when immersed in liquid (e.g., under the same conditions as the substrate will be exposed to radiation). By having a surface of an absorption element of the sensor, that is to be in contact with liquid, formed of no more than one metal type, long life of the sensor may be obtained.

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:
An immersion lithographic apparatus has adaptations to prevent or reduce bubble formation in one or more gaps in the substrate table by preventing bubbles escaping from the gap into the beam path and/or extracting bubbles that may form in the gap.
