Abstract:
PROBLEM TO BE SOLVED: To provide a immersion-type lithography projection apparatus. SOLUTION: In the immersion-type lithography apparatus, an immersion liquid is confined between a final element of a projection system and a substrate. Both of hydrophobic and hydrophilic layers are used on various elements of the apparatus. The use of them helps to prevent air-bubble formation in the immersion liquid, and reduce residues remained on the elements after immersion in the immersion liquid. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projection equipment with a sensor excellent in durability which is used in the immersion type lithography equipment capable of high resolution treatment by pouring liquid of comparatively high refraction index to fill spacing between the final component of the projection system and the substrate and by sinking the substrate into the immersion liquid. SOLUTION: The lithography projection equipment comprises a liquid feed system configured so that immersion liquid may be provided in spacing between the final component of the projection system and the foregoing substrate, and the sensor attached to a substrate table so that it may be exposed by radiation while it is immersed into the immersion liquid supplied by the liquid feed system. The sensor includes an external surface contacted by the immersion liquid while it is irradiated. The external surface of the sensor is formed by continuous layers of one metal format, while the sensor is formed by single or several metal formats. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To disclose a lithography projector in which a space between the final element of a projection system and a substrate is filled with liquid. SOLUTION: Hermetic edge sealing members 17 and 117 surround a substrate W on a substrate table WT or another object at least partially thus preventing the catastrophic loss of the liquid when the edge part of the substrate is imaged or illuminated.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus, capable of reducing an uneven heating effects on an element of a projection system, when using, for example, a local illumination mode, or to provide a method improved for reducing the uneven heating effects. SOLUTION: In the lithographic apparatus, a corrective irradiation step is performed by using an illumination mode arranged so as to heat a selected part on which a large amount of heat is not applied during the production exposure of the element of the projection system close to the pupil plane of the lithographic apparatus. The corrective irradiation step is performed to improve uniformity of optical component heating of the projection system and/or reduce the phase gradient. COPYRIGHT: (C)2008,JPO&INPIT
