  • Patent number: 7871852
    Abstract: A method for fabricating a carbon-enriched film includes the following steps. First, a substrate is provided. Next, a CFx film (fluorinated carbon films) containing carbon-fluoride bonded molecules is formed on the substrate. Next, a treatment process is performed on the CFx film to convert the carbon-fluoride bonded molecules into carbon-carbon bonded molecules.
    Type: Grant

  • 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.

  • Publication number: 20080018242
    Abstract: A method of fabricating a double side emitting organic light emitting diode (OLED) including the following steps is provided. First, a transparent substrate is provided. Then, a first transparent electrode and an organic light emitting layer are sequentially formed on the transparent substrate. Next, a second transparent electrode is formed on the organic light emitting layer. The method of forming the second transparent electrode includes the following steps. A first film composed of alkali metal compound or alkaline-earth metal compound is formed on the organic light emitting layer; a second film composed of metal material is formed on the first film and has a thickness between 20 angstroms and 50 angstroms; a third film composed of transparent conductive material is formed on the second film by using a plasma diffusion deposition process or an ionic thermal evaporation process.
