  • Publication number: 20200212206
    Abstract: In a method of fabricating a nonvolatile memory device according an embodiment, a first tunnel oxide layer, a nitrogen supply layer, and a second tunnel oxide layer having a density lower than that of the first tunnel oxide layer are formed on a substrate. Nitrogen in the nitrogen supply layer is diffused into the second tunnel oxide layer to convert at least a portion of the second tunnel oxide layer into an oxynitride layer.

  • Publication number: 20200071613
    Abstract: Disclosed is a slurry composition for chemical mechanical polishing (CMP) includes, as polishing particles, a complex compound of both fullerenol and alkylammonium hydroxide. The slurry composition, which exhibits excellent polishing properties, may be prepared at low cost in large quantities. Also disclosed is a method of preparing the slurry composition comprising obtaining a mixture of a fullerenol complex compound and unreacted hydrogen peroxide by reacting alkylammonium hydroxide, hydrogen peroxide, and fullerene, removing the unreacted hydrogen peroxide by adding hydrogen peroxide decomposition catalyst particles to the mixture, separating the hydrogen peroxide decomposition catalyst particles from the mixture by filtration, and adding a polishing additive to the mixture.

  • Publication number: 20200052226
    Abstract: An organic light emitting diode comprises an emitting material layer implementing a delayed fluorescence and another emitting material layer disposed adjacently to the emitting material layer and implementing fluorescence or phosphorescence and an organic light emitting device including the diode. As exciton generated in the plural emitting material layer drops to a ground state through the luminous materials each of which has a controlled energy level, it is possible to implement excellent luminous efficiency derived from a delayed fluorescent material and improved color purity derived from a fluorescent or phosphorescent material having narrow FWHM.

  • Patent number: 10541407
    Abstract: The present disclosure provides a method of producing high purity SiOx nanoparticles with excellent volatility and an apparatus for producing the same, which enables mass production of SiOx nanoparticles by melting silicon through induction heating and injecting gas to a surface of the molten silicon. The apparatus includes a vacuum chamber, a graphite crucible into which raw silicon is charged, the graphite crucible being mounted inside the vacuum chamber, an induction melting part which forms molten silicon by induction heating of the silicon material received in the graphite crucible, a gas injector which injects a gas into the graphite crucible to be brought into direct contact with a surface of the molten silicon, and a collector disposed above the graphite crucible and collecting SiOx vapor produced by reaction between the molten silicon and the injected gas.

  • Publication number: 20190371861
    Abstract: An image sensor includes a sensor region for receiving light and generating an image data and a pad region adjacent to the sensor region, an insulation layer on the substrate, and a lower transparent electrode on the insulation layer in the sensor region, and an etch stop layer on the insulation layer in the sensor region and pad region. The etch stop layer may include silicon nitride. A height of an uppermost surface of the lower transparent electrode may be substantially equal to a height of an upper surface of the etch stop layer, with respect to the substrate.
