  • Patent number: 7220468
    Abstract: It is an object to provide a conductive organic thin film having organic molecules that include at one end a terminal bonding group that is covalently bonded to a substrate surface, a conjugate bonding group that is located at any portion of the organic molecules and that is polymerized with other molecules, and a polar functional group that does not include active hydrogen and that is located at any portion between the terminal bonding group and the conjugate bonding group, wherein the organic molecules are oriented and their conjugate bonding groups are polymerized, forming a conduction network. The conductivity (?) of the conductive organic thin film at room temperature (25° C.) is at least 5.5×105 S/cm, and preferably at least 1×107 S/cm, without dopants, having significantly higher conductivity than metals such as gold and silver. In particular, a film of polypyrrole or polythienylene conjugate bonds that is polymerized through polymerization through electrolytic oxidation has high conductivity.

  • Publication number: 20070085076
    Abstract: An organic electronic device of the present invention includes a substrate, at least two electrodes formed on the substrate, a conductive organic thin film that is formed on the substrate and electrically connects the electrodes, and a coating film for coating at least a portion of the electrodes. The conductive organic thin film is a polymer of organic molecules containing a conjugated-bondable group, and one end of each of the organic molecules is chemically bonded to the surface of the substrate and the conjugated-bondable groups in the organic molecules are polymerized with other conjugated-bondable groups to form a conjugated bond chain. The coating film electrically connects the electrodes to the conductive organic thin film and achieves a smaller connection resistance than that in the case where the electrodes and the conductive organic thin film are connected directly.

  • Publication number: 20070080641
    Abstract: An object of the present invention is to reduce power consumption in a plasma display panel (PDP) by reducing the discharge firing voltage, while suppressing the occurrence of discharge variability when the PDP is driven, as well as ensuring the wall-charge holding performance of a protective film surface. To achieve this, a front panel of a PDP of the present invention has a catalyst layer dispersed on a surface of display electrodes formed in stripes on one side of a glass substrate, and needle crystals composed of graphite formed to stand upright on the catalyst layer. The needle crystals form a phase-separated structure with the materials of a dielectric film and a protective film.

  • Publication number: 20060087884
    Abstract: A semiconductor memory device has a nonvolatile memory cell to which data writing operation is limited to a predetermined logic value. In the case of rewriting data “10101010” written in a first memory core to data “01010101”, since the data writing operation includes writing of a logic value “1” opposite to the predetermined logic value, an erasing operation is needed and the data writing is regulated. By rewriting a pointer value stored in a pointer memory in place of performing the erasing operation, an operation of switching a memory core to be selected to a second memory core (data “11111111”) is performed. Data is newly written into the second memory core selected by the rewritten pointer value.

  • Patent number: 6965107
    Abstract: An Al film is formed on a cap wafer and the Al film is patterned into a ring-shaped film. Dry etching is performed by using the ring-shaped film as a mask to form a drum portion enclosing a recess portion to provide a vacuum dome. After forming a depth of cut into the substrate portion of the cap wafer, the cap wafer is placed on a main body wafer having an infrared area sensor formed thereon. Then, the ring-shaped film of the cap wafer and the ring-shaped film of the main body wafer are joined to each other by pressure bonding to form a ring-shaped joining portion.
