    Abstract: A stress liner for use within a semiconductor structure that includes a field effect device has a dielectric constant less than about 7 and a compressive stress greater than about 5 GPa. The stress liner may be formed of a carbon based material, preferably a tetrahedral amorphous carbon (ta-C) material including at least about 60 atomic percent carbon and no greater than C about 40 atomic percent hydrogen. The carbon based material may be either a dielectric material, or given appropriate additional dielectric isolation structures, a semiconductor material.

    Abstract: The organic TFT includes: a gate electrode; source and drain electrodes insulated from the gate electrode; an organic semiconductor layer insulated from the gate electrode and electrically connected to the source and drain electrodes; an insulating layer insulating the gate electrode from the source and drain electrodes and the organic semiconductor layer; and a self-assembly monolayer (SAM) included between the insulating layer and the organic semiconductor layer. A compound forming the SAM has at least one terminal group selected from the group consisting of an unsubstituted or substituted C6-C30 aryl group and an unsubstituted or substituted C2-C30 heteroaryl group.

  • Patent number: 7705528
    Abstract: A halogenated aromatic monomer-metal complex useful for preparing a polymer for electronic devices such as a light-emitting diode (LED) device is described. The aromatic monomer-metal complex is designed to include a linking group that disrupts conjugation, thereby advantageously reducing or preventing electron delocalization between the aromatic monomer fragment and the metal complex fragment. Disruption of conjugation is often desirable to preserve the phosphorescent emission properties of the metal complex in a polymer formed from the aromatic monomer-metal complex. The resultant conjugated electroluminescent polymer has precisely controlled metal complexation and electronic properties that are substantially or completely independent of those of the polymer backbone.

  • Patent number: 7682864
    Abstract: A method for fabricating an organic electroluminescent device (OLED) includes the following steps. First, a substrate is provided. Next, an anode layer is formed on the substrate. Next, a buffer layer is formed on the anode layer, wherein the buffer layer include a CFx film (fluorinated carbon films) containing carbon-fluoride bonded molecules. Next, a treatment process is performed on the CFx film to convert the carbon-fluoride bonded molecules into carbon-carbon bonded molecules. A plurality of organic layers is formed on the buffer layer. A cathode layer is formed on the organic layer. Because the buffer layer has a better conductivity, the organic electroluminescent device (OLED) of the present invention has a better luminous efficiency.

Following processing, the nanowires can be removed from the substrate and transferred to other substrates. The present invention also provides for nanowires produced by these processes and electronic devices comprising these nanowires. The present invention also provides for nanowire growth apparatus that provide horizontal nanowires, and processes for producing nanowire devices.
