Abstract: An apparatus for optically forming a pattern on an object using a reticle having an original pattern to be optically projected. The apparatus is equipped with a storage circuit for storing information indicative of an exposure condition for the reticle, the storage circuit being attached to the reticle. An exposure apparatus reads out the information from the storage circuit so as to project the original pattern of the reticle on the object in accordance with the read information so that a pattern corresponding to the original pattern is formed on the object. This arrangement can automatically and accurately set the exposure condition in the exposure apparatus.

Abstract: This invention is directed to the storing of digital, information, This storage system comprises a number of layers of transparent or translucent material. In each layer there is a chemical or chemicals subject to change by being contacted with different electromagnetic wave lengths. For example, if there be eight layers then the chemical or chemicals in any layer is subject to be changed by an electromagnetic radiation of a wave length different than for any of the other seven layers. In this manner, with eight layers it is possible to have an eight bit byte. Actually, under premutations and combinations it is possible to have as many as eight bit bytes from the eight layers. It is conceivable that there may be more than eight layers such as sixteen layers of thirty-two layers. There is the possibility of storing large amounts of information in a small volumn.

Abstract: Fine, sub-micron line features and patterns are created in a sensitized layer on a semiconductor wafer by a beam of low wavelength radiation, such as X-rays or Gamma-rays. A continuous stream of such radiation is gated on and off by a shutter mechanism comprising a distortable-surface device and a beam-blocking device. The distortable-surface device is a surface acoustic wave device, a magnetostrictive device, or the like. The beam-blocking device is a beam stop, such as a knife edge, an aperture, or the like. The distortable-surface device can be selectively caused to reflect an incident beam of radiation past or into the beam-blocking device. In this manner, a continuous stream of radiation, such as from a pellet of Cobalt-60, can be quickly and precisely gated on and off to impact and to not-impact the semiconductor wafer, respectively. By moving either of the reflected beam or the semiconductor wafer, line features can be created in the sensitized layer on the semiconductor wafer.

Abstract: A film archival storage holder comprises base and cover sheets in a laminar page configuration including a plurality of pockets formed with bonding lines for holding the film. The pockets have an opening at one end accessed through a slit in the cover sheet for placing the film within the pocket and a smaller opening at the other end for accessing the pocket and maneuvering the film into a desired position. The smaller opening prevents the film from exiting the pocket. A flap is formed between the slit and another bonding line parallel to the slit. Once in the pocket, the film is maneuvered under the flap for locking the film within the pocket. The film can be positioned between the slit and the smaller opening and the film image with unobscured view which is especially useful when making contact prints from negative film placed in the pockets. Negative film in strips of any length can be stored and maneuvered into a predetermined position for storing or exposing.
