Abstract:
PROBLEM TO BE SOLVED: To provide an optical patterning device and its method that improves luminance and phase modulation characteristics of an individually controllable element array. SOLUTION: A light patterning system comprises an illumination system that supplies a beam of radiation having a certain wavelength λ. An array of reflective pixels patterns the beam, wherein the array includes pixels having at least a first tilting mirror that is logically coupled to a second tilting mirror. In an embodiment, the first and second tilting mirrors are (i) substantially adjacent to each other, and (ii) offset in height from each other by a first mirror displacement. A projection system is included that projects the patterned beam onto a target. In alternate embodiment, the array of reflective pixels includes pixels having first through fourth tilting mirrors that are logically coupled to each other. The first through fourth tilting mirrors are (i) respectively offset in height from a reference plane by first through fourth mirror displacements, and (ii) are respectively arranged clockwise in a substantially square pattern.

Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method used to direct a radiation beam to illuminate non-perpendicularly a patterning array of individually controllable elements used for patterning the radiation beam. SOLUTION: The individually controllable elements can change a telecentricity of the radiation beam. Projection of the radiation beam onto the individually controllable elements can be by a concave mirror or use a folding mirror placed in an object field of the individually controllable elements. Alternatively, the individually controllable elements can change the optical axis of the radiation beam. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a lithography apparatus constituted high in reliability of accuracy and a quality of generating image which can reduce pattern inspection time after exposure, and/or re-working amount. SOLUTION: In the lithography apparatus using an array of element possible to be controlled independently, the quality of the generating image is inspected by converting a fraction (portion) of strength of radiation beam patternized by the array of the element, into an image sensor.

PROBLEM TO BE SOLVED: To provide apparatus and a method of lithography used for exposing a pattern on a substrate, the pattern having improved uniformity of a critical dimension. SOLUTION: The lithography apparatus forms a pattern of radiation beams using an array of elements which are independently controllable. Pattern data provided to the array of independently controllable elements are adjusted to correct change in processing. Consequently, uniformity of a critical dimension of a substrate on which the pattern is formed is improved by using the apparatus. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a structure, in which one or more patterning arrays are provided so as to reduce the nonflatness of the patterning arrays in a lithographic apparatus. SOLUTION: One or more programmable patterning arrays are mounted to a mounting plate via height-adjustable mounting structures so as to allow the flatness of the active surfaces of the patterning arrays to be controlled. The height-adjustable structures include an array of piezoelectric actuators or screws. Alternatively, the backsides of the patterning arrays are polished to optical flatness and are bonded to an optically flat surface of a rigid mounting body through crystal bonding.

Abstract:
PROBLEM TO BE SOLVED: To obtain a lithographic device capable of easily providing data to individually controllable array-like elements, regardless of the size change of repeating unit of patterns exposed on a substrate. SOLUTION: The proportion of programmable patternization means used for the patternization of the substrate is restricted so as to allow the size of the repeating pattern, exposed to the substrate to be an integral number of times the size of the pattern exposed on the substrate by patternizing beams.

PROBLEM TO BE SOLVED: To provide equipment and method that enable speedy and reliable calibration by a programmable pattern forming means using measured values preferably measured at a substrate level. SOLUTION: A lithographic equipment, calibration method and device manufacturing method are obtained. For the purpose of calibration for a lithographic equipment with a programmable pattern forming means, this equipment uses a sensor, such as a CCD, CMOS sensor, and optical diode and the like that has a detector element larger than the size of a spot corresponding with the single pixel of the pattern forming means. Pixels are selectively excited on a single base or on a group base. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of using for the manufacture of an integrated circuit and other (semiconductor) devices as a commercially charming alternative plan instead of using a conventional lithographic projector (a method using a mask). SOLUTION: The imaging apparatus comprises a radiant ray system for supplying a projection beam of radiant ray, a supporting structure for supporting a pattern forming means effecting a pattern formation in accordance with the desired pattern, a substrate table for retaining a substrate, and a projection system for projecting a beam formed through the pattern formation on the target part of the substrate. The pattern formation means comprises a plurality of individual pattern formation subelements to produce subbeams formed through pattern formation, by using respective subelements. The imaging apparatus comprises a combining means for combining a plurality of subbeams formed through the pattern formation, to a single image formed through the pattern formation.
