  • Patent number: 8963421
    Abstract: An electroluminescent device includes: a substrate; an electroluminescent layered structure disposed over the substrate and including first and second electrode layers and an electroluminescent material layer disposed between the first and second electrode layers; and a moisture barrier layer in contact with the electroluminescent layered structure for preventing moisture from diffusing into the electroluminescent layered structure. The moisture barrier layer includes at least two inorganic films of a silicon-nitrogen-containing compound and at least one polymer film interposed between the inorganic films.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: February 24, 2015
    Assignee: National Chiao Tung University
    Inventors: Jihperng Leu, Shu-Hao Syu, Hung-En Tu, Chih Wang

  • Publication number: 20130330482
    Abstract: The present invention relates to carbon-doped silicon nitride thin film and forming method and device thereof The carbon-doped silicon nitride thin film is prepared by using a precursor having at least one of bis(dimethylamino)diethylsilane, N,N-Dimethyltrimethylsilylamine and a cyclic structure with a N—Si bond. The method for forming a carbon-doped silicon nitride thin film includes: providing a precursor having at least one of bis(dimethylamino)diethylsilane, N,N-Dimethyltrimethylsilylamine and a cyclic structure with a N—Si bond to form the carbon-doped silicon nitride thin film. The device for forming the carbon-doped silicon nitride thin film includes a reactor and a container with the aforementioned precursor coupled to the reactor.
