PROBLEM TO BE SOLVED: To provide a 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 on the imprintable medium, and then the first and second templates are removed from the imprinted medium.
Abstract:
PROBLEM TO BE SOLVED: To reduce the distortion of an image due to the temperature gradient of a substrate and an immersion liquid, in a liquid immersed projection exposure apparatus. SOLUTION: In an immersed lithographic apparatus including a temperature control unit for adjusting the temperature of a member in the final state of a projection exposure apparatus PL, a substrate, and an immersion liquid to a common target temperature T4, the temperature gradient is reduced, by adjusting the total temperature of these constituent components. By doing so, the matching properties of image formation and the total performance are improved. The means to be used includes a control of the flow rate of the immersion liquid and the temperature by a feedback circuit. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus for reducing a remaining liquid on a surface of a substrate after exposure by a projection system. SOLUTION: In this lithographic apparatus, a localized area of the substrate surface under a projection system PL is immersed in liquid. The height of a liquid supply system 310 above the surface of the substrate W can be varied using actuators 314. A control system uses feedforward or feedback control with input of the surface height of the substrate W to maintain the liquid supply system 310 at a predetermined height above the surface of the substrate W.

Abstract:
PROBLEM TO BE SOLVED: To solve a problem that since template holders occupy a significant amount of space in an imprint lithography apparatus, there is not sufficient space to provide an imprint template to imprint every imprint area at the same time. SOLUTION: The imprint lithography apparatus has a first array of template holders, a second array of template holders, and a substrate table arranged to support a substrate to be imprinted, wherein the first array of template holders is arranged to hold an array of imprint templates that can be used to imprint a first array of patterns onto the substrate, and the second array of template holders is arranged to hold an array of imprint templates that can be used to imprint a second array of patterns onto the substrate, the patterns imprinted by the second array being interspersed between the patterns imprinted by the first array.

Abstract:
PROBLEM TO BE SOLVED: To provide an imprint lithography device which solves the problem of the shortage of the space for forming imprint templates when imprinting each imprint area at the same time, since a template holder occupies space significantly. SOLUTION: The imprint lithography device comprises a first array of template holders, a second array of template holders, and a substrate table arranged for supporting a substrate to be imprinted. The first array of template holders is arranged for holding an array of imprint templates that can be used for imprinting a first array of patterns onto the substrate. The second array of template holders is arranged for holding an array of imprint templates that can be used for imprinting a second array of patterns onto the substrate. The patterns imprinted by the second array are interspersed between the patterns imprinted by the first array. COPYRIGHT: (C)2007,JPO&INPIT

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 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.
