  • Patent number: 8361845
    Abstract: An object is to provide a method for manufacturing a semiconductor device which suppresses an influence on a semiconductor element due to entry of an impurity element, moisture, or the like from outside even in the case of thinning or removing a substrate after forming a semiconductor element over the substrate. A feature is to form an insulating film functioning as a protective film on at least one side of the substrate by performing surface treatment on the substrate, to form a semiconductor element such as a thin film transistor over the insulating film, and to thin the substrate. As the surface treatment, addition of an impurity element or plasma treatment is performed on the substrate. As a means for thinning the substrate, the substrate can be partially removed by performing grinding treatment, polishing treatment, or the like on the other side of the substrate.

  • Publication number: 20120326143
    Abstract: A light-emitting device in which reduction in performance due to moisture is suppressed is provided. The light-emitting device has a structure in which a partition having a porous structure surrounds each of light-emitting elements. The partition having a porous structure physically adsorbs moisture; therefore, in the light-emitting device, the partition functions as a hygroscopic film at a portion extremely close to the light-emitting element, so that moisture or water vapor remaining in the light-emitting device or entering from the outside can be effectively adsorbed. Thus, reduction in performance of the light-emitting device due to moisture or water vapor can be effectively suppressed.

    Abstract: A conductive layer serving as an auxiliary wiring is formed under a first electrode with a first insulating layer interposed therebetween, and the conductive layer and a second electrode are electrically connected to each other through an opening in the first insulating layer and the first electrode. A second insulating layer is formed over a sidewall of the opening so that the first electrode is not directly in contact with the second electrode in the opening. An EL layer is formed by evaporation in a state where a deposition target substrate is inclined to an evaporation source, so that the second insulating layer serves as an obstacle and a region where the EL layer is not formed by the evaporation and the conductive layer is exposed is formed in part of the opening in a self-aligned manner.

  • Publication number: 20120199869
    Abstract: To provide a light-emitting device having a top-emission structure with low power consumption. A convex structure body is formed over a substrate to be provided with an organic EL element, and then an upper electrode layer is formed. Thus, the upper electrode layer has a shape following the convex shape. In addition, a conductive layer is formed over a substrate sealing an organic EL layer. Then, by sealing a surface where the upper electrode layer is formed and a surface where the conductive layer is formed are sealed to face each other, at least part of the electrode layer overlapped with the convex structure body is in contact with the conductive layer, so that the resistivity of the upper electrode layer is significantly reduced. Thus, power consumption of a light-emitting element can be reduced.
