An exposure method for exposing a pattern formed on a reticle onto an object includes a flatness measurement step for measuring the flatness of the object and storing the information obtained, a position measurement step for measuring positions at plural points on the object, and a changing step for changing at least one of the position and tilt of the object on the basis of the information obtained by the flatness measurement step, and information on the position obtained by the position measurement step.
Abstract:
A system for quickly and easily optimizing the parameters of an industrial machine or solving any trouble in industrial machine is provided. A factory (100) and vendor (200) are connected through a data communication network (300). A management apparatus (120) selectively gives the operation right of an industrial machine (110) to a factory-side operation apparatus (130) or a vendor-side operation apparatus (210) arranged at a remote site. The operation apparatus having the given operation right can operate the industrial machine (110) and obtain information representing the operation condition of the industrial machine.
Abstract:
A pattern exposure and transfer method wherein a reticle has a pattern, including a chromium pattern, to be transferred, the chromium pattern of the reticle having a thickness, with respect to a wavelength .lambda., which is approximately N.multidot..lambda./2 or N.multidot..lambda., where N is a positive integer. The reticle is illuminated with light having a center wavelength .lambda., whereby the pattern of the reticle is transferred onto a photosensitive substrate through a projection optical system. The transfer of the reticle pattern is executed in a state of illumination .sigma. such that no sub-peak appears in an optical image.
Abstract:
A position detection device for detecting the position of an object includes a light source for generating light, an illumination device introducing the light from the light source to the object, and a detector for detecting the position of the object on the basis of a sensed optical image. The detection device further includes an image forming optical system for forming the image of the object on a detection surface of the detector at a first magnification. The device also includes an optical member insertable into and retractable from an optical path of the light travelling from the object to the detector. Insertion of the optical member into the optical path allows the light from the object which has been passed through at least part of the optical member and the image forming optical system to form the image of the object on the detection surface of the detector at a second magnification smaller than the first magnification.
Abstract:
An alignment method and a pattern forming method using the same, wherein a substrate onto which a complete pattern is to be transferred is held by a holder having formed thereon at least two alignment marks disposed in a predetermined positional relation with each other. Separate masks having relatively complementing pattern segments are used. Each of the masks is aligned with corresponding portion of the holder through an associated one of the alignment marks. As the result, the pattern segments transferred onto the substrate is aligned with each other and the continuity of the pattern is assured on the substrate. Also provided is an alignment mark forming method and a pattern forming method using the same, wherein the region on a substrate in which a continuous pattern is to be formed is divided into at least two sections and alignment marks for these sections are simultaneously formed on the substrate by means of one single mask, so that the segments of the pattern which are first to be transferred onto the sections of the substrate can be aligned with each other when they are transferred onto the substrate.
Abstract:
An optical device includes an objective lens, a relay lens group for relaying the beam from the objective lens, and a compensator for compensating the variation in the optical path length, which occurs when the relative position between said objective lens and said relay lens group changes, by expanding or contracting the optical path.
Abstract:
An apparatus and method for position detection for an object having a detection pattern formed by a concavity or convexity. The position detecting apparatus includes a scanning system for scanning the object with a light beam, a photoelectric transducer for receiving the information light reflected from the detection pattern to produce an electric signal, and a processing unit for computing, on the basis of the electric signal, the position of the detection pattern. Unwanted components included in the information light are prevented from being received by the photoelectric transducer, or electric signals corresponding to the unwanted components are excluded, so that the accuracy of signal processing and the accuracy of position detection are improved.

Abstract:
An imprint apparatus for pressing resin and a mold to each other in a Z-axis direction to form a resin pattern on a shot region includes: a mold chuck; an X-Y stage; a reference mark formed on the stage; a first scope configured to measure a positional deviation in an x-y plane between a mold mark and the reference mark; a second scope configured to measure a position of a substrate mark in the plane not via the mold mark; and a dispenser configured to dispense resin. In the plane, the dispenser center is deviated in position from the mold chuck center by a first distance in a first direction, and the second scope center is deviated in position from the dispenser center by a distance smaller than twice the first distance in the first direction or a second direction opposite thereto.
