Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projection apparatus in which the space between the final element of a projection system, where the liquid loss from a supply system is minimized during exposure of the edge part of a substrate, and the substrate is filled with a liquid.SOLUTION: An edge sealing member 17 has an upper primary surface which is substantially in flush with the upper primary surface of a substrate W, and surrounds the substrate W or other object on a substrate table at least partially. Consequently, catastrophic liquid loss is prevented when the image at an edge part of the substrate W is captured or the edge part is illuminated even if the section under a projection lens PL is operated.

Abstract:
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 adjust a conventional lithography equipment to an environment of immersion. SOLUTION: In the lithography projection equipment, a liquid supply system and an object W on a substrate table WT are arranged to prevent a high-speed immersion liquid from flowing onto a sensor S.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography equipment of enhanced productivity. SOLUTION: The stage equipment holds two pattern forming apparatus 42 and 43. The pattern forming apparatus are so arrayed that the distance between patterns in scanning direction agrees with the length of the pattern in the scanning direction. So, a first chip is exposed with a first pattern 44, and a second chip that adjoins the first chip is skipped. Then a second pattern 45 is used to expose a third chip that adjoins the second chip, for an improved exposure sequence. COPYRIGHT: (C)2007,JPO&INPIT
