Abstract:
PROBLEM TO BE SOLVED: To provide a pattern onto a non-traditional substrate by a novel method with use of a novel substrate carrier and a substrate carrier. SOLUTION: According to one of the aspects of the present invention there is provided a substrate carrier arranged to hold a substrate in a given position using a vacuum, the vacuum being established in a sealed space created between the substrate carrier and the substrate. According to a second aspect, there is provided a method of removably securing a substrate to a substrate carrier, including: positioning a substrate on the substrate carrier so that a sealed space can be defined between the substrate and the substrate carrier; and establishing a vacuum in the space between the substrate and the substrate carrier.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projection apparatus in which a space between the substrate and projection system is filled with a liquid while minimizing the volume of the liquid that must be accelerated during stage movements. SOLUTION: In the lithographic projection apparatus, a seal member surrounds a space between the final element of the projection system and a substrate table of the lithographic projection apparatus. A gas seal is formed between the seal member and the surface of the substrate to contain the liquid in the space. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a pattern forming device, a printer, and a device manufacturing method which achieve low manufacturing and usage cost, and imprinting in nanometers. SOLUTION: By using a bent member, on which a stamp surface having a pattern, is supported, the bent member is rolled on a substrate to be printed. A resist layer is formed on the substrate. An irradiation system is further provided for irradiating a contact region in between the stamp surface and the substrate. The resist layer is cured in a predetermined region by irradiation light irradiated through the pattern, and imprinting in nanometers is enabled. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a device, which minimizes or eliminates at least a portion of error sources in positional adjustment of adjacent exposure portions. SOLUTION: A projection field is selected so as to minimize a stitching error, in order to print a layer of an extended device, i.e., a device extending into a plurality of target portions or dies. It is desirable that the projection field is selected based on the data characterizing a used projection lens, and in such a way that the difference between positional errors of a projected image at the side opposite to the field is minimized.

Abstract:
PROBLEM TO BE SOLVED: To provide lithography capable of a high resolution imprint.SOLUTION: An imprint method is disclosed. In one example, separated first and second target regions made of an imprintable medium on a substrate are brought into contact with first and second templates, respectively, to form first and second imprints in the imprintable medium, and then the first and second templates are removed from the imprinted medium.
Abstract:
PROBLEM TO BE SOLVED: To reduce image distortion due to temperature gradients in a substrate and immersion liquid in an immersion projection exposure apparatus.SOLUTION: An immersion lithography apparatus comprises a temperature controller configured to adjust temperature of a member in the final stage of a projection exposure apparatus PL, a substrate, and immersion liquid to common target temperature T4. Imaging consistency and whole performance can be improved, by adjusting all of the temperatures of these structural members and by reducing temperature gradients. Means used to adjust the temperature may include controlling a flow rate and the temperature of the immersion liquid via a feedback circuit.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projector in which the space between a final element of a projecting system and a substrate is filled with a liquid. SOLUTION: An edge sealing member 17 surrounds at least a part of a substrate W or other objects on a substrate table WT to prevent catastrophic liquid loss, when the edge of the substrate is imaged or illuminated.
