    Abstract: A chuck 10 which supports a substrate 1 is moved by using an X-direction stage 5, and a position of the chuck 10 is detected at the same time. A traveling error of the X-direction stage 5 is detected according to a detecting result of position of the chuck 10. Then, a coordinate of drawing data supplied to a driving circuit 27 of a light beam irradiation device 20 is modified according to a detecting result of the traveling error of the X-direction stage 5, and the patterned data having the modified coordinate is supplied to the driving circuit 27 of the light beam irradiation device 20. Even if the traveling error such as shifting or yawing occurs in the X-direction stage 5, patterns can still be precisely drawn.

    Abstract: A stage device includes a reaction-force-discharging structure in which a stationary member of a driving mechanism configured with a linear motor and the like disposed in a wafer chamber is connected to an external frame while maintaining the wafer chamber in a hermetic state. When a wafer stage is driven by the linear motor, a reaction force generated by driving the stage is applied to the stationary member. The reaction force is discharged to, e.g., a floor by the reaction-force-discharging structure via an external frame. For example, when the wafer chamber is set to a predetermined atmosphere of gas (including air from which organic substances and the like have been removed), the reaction force caused by driving the wafer stage can be discharged to the outside while maintaining the predetermined atmosphere. In an exposure apparatus using the stage device, accurate exposure is possible by reducing effects of vibration to the greatest extent possible.

The platen is divided into controllable segments defined by an electrode pattern formed within the platen itself. These segments can each be selectively made transmissive or opaque by applying appropriate voltages to the segment electrodes. An advantage of the invention is that it can operate without a platen cover, since the area of the platen not covered by the original can be made opaque. The opaque part of the platen directs imaging light back into the system, shielding a user's eyes and helping to create a white background if the platen is imaged.

  • Patent number: 6337735
    Abstract: An exposure apparatus for photoengraving stamps includes a light-proof cabinet having a flash light therein and a drawer adapted to be drawn out therefrom. A clamp is carried on the drawer for holding the stamp. The clamp includes a base fixed to the drawer and formed with a pair of parallel rails, a pair of opposed holders movable on the base along the parallel rails, and means for moving the holders along the parallel rails in opposite directions synchronously. Each of the holders is also provided with a lifter for lifting up the middle plank between the bars and a handle for operating the lifter. Therefore the stamp may be held between the planks just under the flash light when the holders are moved closer together and the middle planks are lifted by turning the handles.

  • Patent number: 6320650
    Abstract: A method and apparatus for capturing an image. The apparatus includes a support platen for receiving a document having a front image bearing side and a back side co-extensive with the front side. An image capture element is disposed below the platen for capturing an image on the front image side. A reticle forming device is provided for providing a reticle on the platen for assisting in positioning of the document when a positioning cover is placed over the document. A second cover is also provided for placement over the positioning cover. The second cover is substantially opaque and is used for when the image on the front image side is illuminating for capture of the image.

  • Patent number: 6295119
    Abstract: A scanning exposure apparatus of the scan-and-stitch type for stitching and forming a plurality of pattern images while partially superimposing them on a photosensitive substrate along a direction perpendicular to a scanning direction. The apparatus includes a fixed field diaphragm for setting a width of an illumination area in the scanning direction on the mask, and a variable field diaphragm comprising third and fourth shielding plates for restricting the width of the illumination area in the scanning direction, and first and second shielding plates which are rotationally movable in a plane perpendicular to an optical axis of an illumination optical system for setting a width of the illumination area in the direction perpendicular to the scanning direction. Scanning exposure is performed while each of the first and second shielding plates maintains an identical rotational angle over a connecting area of an image-plane stitching section.

  • Publication number: 20010008440
    Abstract: An optical element (1) of an optical system has at least one chamber (5) that is sealed against atmospheric pressure and is enclosed by boundary surfaces and that has a fluid filling. At least one of the boundary surfaces of the chamber (5) is exposed at least partially to illumination light. It is configured so that a change in the fluid pressure inside the chamber (5) results in a change in non-rotational-symmetric imaging properties of the optical element (1) having n-fold symmetry. For this purpose, a fluid source has a fluid connection to the chamber via a fluid supply line (17). Furthermore, a control device is provided for the pressure in the fluid filling.

  • Patent number: 6081346
    Abstract: The present invention allows formation of an image having an excellent finish quality by using an extremely simple and low-cost structure. Linearly polarized light transmitted through each of liquid crystal cells of a liquid crystal panel is made into circularly polarized light by a quarter-wave phase plate, and thereafter, the circularly polarized light is used to expose a photographic printing paper via lithium-niobate prisms serving as a birefringent filter. As a result, light transmitted through a light transmitted area of each of the liquid crystal cells is irradiated on a region on the photographic printing paper corresponding to a light non-transmitted area so as to prevent formation of a pattern caused by the light non-transmitted area.

  • Patent number: 6072563
    Abstract: Printer throughput is increased in a printer that prints sequential images on a film strip onto a matching strip of photosensitive printing paper. A film gate supports two or more images on the film strip. An illuminator provides light to the images in the film gate. An optics system focuses the film images onto separable areas of the printing paper and a shutter over each printing area individually exposes the printing areas.

  • Patent number: 6040096
    Abstract: In order to reduce mask pattern transfer error caused by expansion of the mask substrate during transferring the circuit pattern onto the photosensitive substrate, a mask substrate is loosely supported on a plurality of mounts on the mask stage so that the mask substrate can freely expand in response to changes in its temperature. A measuring instrument (such as a temperature sensor or an interferometer) is used to measure a value representing the expansion amount of the mask substrate. Alignment and positioning of the mask substrate and the photosensitive substrate is adjusted in response to the expansion amount of the reticle, based on the measured value.
