  • Patent number: 7952272
    Abstract: In an EL element including a light emitting layer sandwiched between upper and lower electrodes, of light emitted therefrom, light totally reflected at a light emitting layer interface is not taken out, so there is a problem in that light emission efficiency reduces. Therefore, a light scattering layer in which metal particles are dispersed is provided between an electrode and the light emitting layer. According to such a structure, the light from the light emitting layer can be scattered by the metal particles and taken out, thereby improving the light emission efficiency. When plasmon is excited in the metal particles, light confined in the light emitting layer or each layer adjacent thereto can be used, thereby improving light use efficiency.

  • Publication number: 20070062648
    Abstract: A difficulty has been given, that is, in a condition that an electrostatic chuck having an oxide layer as a dielectric layer is set in catalytic chemical vapor deposition apparatus, as a silicon thin film is repeatedly deposited on a workpiece held by the electrostatic chuck, adsorbing power of the electrostatic chuck is gradually decreased, and finally the chuck does not adsorb a substrate at all. Thus, a dielectric layer on a surface of the electrostatic chuck is covered with an insulating film containing silicon nitride or silicon oxide. Thus, since damage to a chuck surface can be prevented, the damage being due to hydrogen radicals generated during depositing the silicon film by the catalytic chemical vapor deposition apparatus, even if the silicon film is repeatedly deposited, power for adsorbing the substrate is not decreased, and consequently substrate temperature is stabilized during depositing the silicon film.

  • Publication number: 20070048895
    Abstract: An organic electronic device using an extremely thin substrate is manufactured by a simple and easy method. That is, according to the method of manufacturing the organic electronic device of the present invention, a first surface of a substrate is subjected to polishing, a protective layer is provided on the first surface, and a second surface on the back side of the first surface of the substrate is removed through etching to reduce the thickness of the substrate. As a result, the extremely thin substrate may be formed. Two extremely thin substrates manufactured through the above process are arranged such that etching surfaces thereof are opposed to each other. Then, the two substrates are bonded to each other so as to hold a layer containing a polymer material therebetween. Thereafter, the protective layer is removed. Accordingly, the organic electronic device is formed on the first surface from which the protective layer has been removed.

  • Publication number: 20060009017
    Abstract: Conventional methods of crystallizing a semiconductor film through scanning with a pulse laser have had a problem in that variation in particle diameter or shape of a crystal grain causes variation in characteristics of a thin film transistor, which lowers display quality of a liquid crystal display. In view of this, in a method of crystallizing a semiconductor film according to the present invention, after a step of performing scanning with a first pulse laser, scanning with a second pulse laser, which has a higher energy density than that of the first pulse laser, is performed in a substantially orthogonal direction to a traveling direction of scanning with the first pulse laser. With this method, the semiconductor film can be crystallized uniformly.
