  • Patent number: 5330592
    Abstract: The present invention relates to novel compounds that exhibit unusually low electrical resistivity at room temperature. More specifically, it has been discovered that the incorporation of at least 1 to 15 atomic percent of gallium and/or at least 1 to 15 atomic percent gold into stoichiometric copper germanide (Cu.sub.3 Ge) compound results in a room temperature resistivity comparable to elemental copper, but with superior chemical and electronic stability upon exposure to air or oxygen at high temperatures. Furthermore, the compounds of the present invention have none of the problems associated with the diffusion of copper into elemental and compound semiconductors which oftentimes lead to the degradation of the semiconductor device characteristics. Additionally, the present invention relates to a method of preparing the novel compounds mentioned previously hereinabove.

  • Patent number: 5294518
    Abstract: A method and apparatus for storing data is provided incorporating an amorphous solid having covalent bonds and a first index of refraction and an energy source for thermally heating selected areas of the amorphous solid to change the index of refraction without melting or substantially crystallizing the amorphous solid. The invention overcomes the problem of corrosion, moisture, or microbial attack resulting in deterioration of the storage medium over time, i.e., 100 years.

  • Patent number: 5281447
    Abstract: The invention is directed to a method for forming a metal coating on a substrate by applying an oxalate of a Group VIII element from the Periodic Table of the Elements to the substrate. The oxalate is selected so that it will decompose to a complex of a zero valent Group VIII element or a Group VIII element on exposure to an energy source. Microelectronic circuits, etch masks or metal contacts on superconductors can be formed by the method when the oxalate coating is exposed to an energy source through a mask or the energy source beamed at the oxalate to trace a pattern on it.The metal thus obtained can be subsequently coated by electroless compositions especially where the Group VIII element is a catalyst for electroless coatings such as palladium. Additionally, the metal coating may be coated by an electrolytic composition.

  • Patent number: 5239504
    Abstract: A data storage system is described which includes a magnetostrictive, anisotropic, ferromagnetic film whose domains exhibit a preferred orientation and are initially poled in one direction along the preferred orientation. A field is applied in opposition to the one direction, the field being insufficient to cause a switching of the poled domains. An electrostrictive film is placed in contact with the ferromagnetic film and a writing system is provided to actuate the electrostrictive film to impart stresses to the ferromagnetic film at selected locations. The induced stresses reduce the anisotropy energy of the ferromagnetic film at the selected locations and enable the domains thereat to become poled in accordance with the applied field. In one version of the invention, the writing means comprises a directed energy beam such as a laser or electron beam. In another version, the writing system employs surface acoustic waves in combination with a scanned energy beam.

  • Patent number: 5134460
    Abstract: A semiconductor chip carrying integrated circuits has lead lines terminating in conductive terminal pads exposed to the exterior through openings in a passivation layer. The pads include pedestals or bumps extending up from them. Each of the pedestals includes a thin metallic adhesion layer deposited on the pad. A thick metallic layer of aluminum or an alloy of aluminum is deposited upon said thin metallic adhesion layer. The thick metallic layer includes at least one metal selected from the group consisting of aluminum, aluminum plus a small percentage of Cu, Ni, Si, or Fe. Several other alternative metals can be added to aluminum to form an alloy. The thick metallic layer forms the bulk of the height of the pedestal. An adhesion layer is deposited on the bump of aluminum composed of a thin film of titanium or chromium. A barrier layer is deposited on the adhesion layer composed of copper, nickel, platinum, palladium or cobalt.

  • Patent number: 4436797
    Abstract: An improved X-ray lithography mask has been fabricated by forming an X-ray absorbing lithography pattern on a supporting foil of hydrogenated amorphous carbon. The substrate foil is formed by depositing a carbon film in the presence of hydrogen onto a surface having a temperature below 375.degree. C. The hydrogen concentration is maintained sufficiently high that the resulting film has at least one atom percent of hydrogen. A film having about 20 atom percent of hydrogen is preferred. While impurities are permitted, impurities must be maintained at a level such that the optical bandgap of the resulting film is at least one electron volt. A film with an optical bandgap of about 2 electron volts is preferred.

  • Patent number: 4384761
    Abstract: A controllable magnetic field influences the position or shape or density distribution of a ferrofluid so that the ferrofluid causes or prevents the coupling of light between optical paths either by physically causing movement of a waveguide (e.g., optical fiber) or by itself physically moving into or out of a coupling region between optical paths.
