PROBLEM TO BE SOLVED: To provide an 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)2009,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projection apparatus and a device manufacturing method, capable of compensating for or improving the effect of a thick pellicle. SOLUTION: The thick pellicle is used to calculate corrections to be applied in exposure so that the thick pellicle is allowed to have a non-flat shape, and the shape compensates for the optical effect of the pellicle. In order for the pellicle to more readily compensate for, to be mounted, in such a manner as to employ a one-dimensional shape under the influence of gravity. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a controller for improving iso-dense bias of lithographic equipment. SOLUTION: The lithographic equipment comprises a lighting system for supplying a projection beam of radiation, a projection system for projecting a patterned beam on a target position of a substrate, a substrate table for holding the substrate, and a controller for adjusting the spectrum distribution of radiation intensity of the projection beam. The adjustment of the spectrum intensity distribution is based on the data 150 associated with iso-dense bias, and the spectrum intensity distribution is adjusted by widening the spectrum band width or by changing the shape 153 of the spectrum intensity distribution.

PROBLEM TO BE SOLVED: To provide a method of effectively cleaning an immersion lithographic equipment. SOLUTION: The immersion lithographic equipment comprises a substrate so configured as to hold a substrate, a projection system configured to project a patterned radiation beam onto the substrate, a megasonic transducer configured to clean a surface, and a liquid supply system configured to supply a liquid between the megasonic transducer and the surface to be cleaned. The surface of the immersion lithography projector is cleaned using megasonic waves generated from the megasonic transducer configured to clean the surface. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projector which reduces the number of man-hours required to exchange a reticle with a pellicle, with a reticle without a pellicle. SOLUTION: In the present projection system, the pattern surface on the reticle is lightened so that a projected image that focuses on an image-forming surface can be obtained. If a pellicle exists in an optical path, a substantial shift occurs in the position of the pattern surface of the reticle. It is necessary to adapt the image-forming surface of the projected image for a proper focus depending on the presence or absence of the pellicle. A corrector moves the position of the pattern surface, thereby the substantial shift of the pattern surface due to the pellicle is removed. COPYRIGHT: (C)2004,JPO&NCIPI
