  • Patent number: 7488625
    Abstract: A three-dimensional, field-programmable, non-volatile memory includes multiple layers of first and second crossing conductors. Pillars are self-aligned at the intersection of adjacent first and second crossing conductors, and each pillar includes at least an anti-fuse layer. The pillars form memory cells with the adjacent conductors, and each memory cell includes first and second diode components separated by the anti-fuse layer. The diode components form a diode only after the anti-fuse layer is disrupted.
    Type: Grant

  • Patent number: 6844663
    Abstract: A structure for a multilayer electrode. Specifically, in one embodiment, a multilayer electrode for a flat panel display device is disclosed. The multilayer electrode comprises a metal alloy layer and a protective layer. The metal alloy layer includes neodymium having a concentration of between greater than three atomic percent and six atomic percent. The protective layer is disposed above the metal alloy layer to form a multilayer stack. The multilayer stack is etched to form the multilayer electrode.

  • Patent number: 6764366
    Abstract: An electrode structure for a display that includes lower electrodes and upper electrodes. In one embodiment, lower and upper electrodes are formed of either an aluminum alloy or a silver alloy. In another embodiment, upper and lower electrodes are formed using a metal alloy layer over which a cladding layer is deposited. A silicon nitride passivation layer is used to protect the upper electrodes from damage in subsequent process steps. Various other materials and structures are also disclosed that protect the upper electrodes from damage in subsequent process steps.

  • Publication number: 20040018731
    Abstract: A method of making a silicon-based electronic device is provided. The method includes, for example, the steps of forming a doped silicon layer on a surface of a substrate material and forming an undoped silicon capping layer on the doped silicon layer. The thin “capping” layers of undoped silicon prevent outgassing of the dopants underneath the cap. In this manner, the next deposition of doped silicon is not subject to autodoping by the previous doped silicon deposition.

  • Patent number: 6448708
    Abstract: A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a cathodic structure which is formed within an active area on a backplate. The cathodic structure includes a emitter electrode metal composed of strips of aluminum overlain by a layer of cladding material. The use of aluminum and cladding material to form emitter electrode metal gives emitter electrode metal segments which are highly conductive due to the high conductivity of aluminum. By using a suitable cladding material and processing steps, a bond between the aluminum and the cladding material is formed which has good electrical conductivity. In one embodiment, tantalum is used as a cladding material. Tantalum forms a bond with the overlying resistive layer which has good electrical conductivity. Thus, the resulting structure has very high electrical conductivity through the aluminum layer and high conductivity into the resistive layer.
