  • Publication number: 20050274964
    Abstract: Disclosed is a light emitting diode structure including a Constructive Oxide Contact Structure contact layer. The light emitting diode structure comprises a substrate, a buffer layer formed on the substrate, a lower confinement layer formed on the buffer layer, a light emitting layer formed on the lower confinement layer, an upper confinement layer formed on the light emitting layer, a Constructive Oxide Contact Structure contact layer formed on the upper confinement layer whose conducting type can be P-type, N-type, or I-type, a first electrode, and a second electrode (transparent electrode). The transparent electrode is formed on the Constructive Oxide Contact Structure contact layer as an anode of the light emitting diode. The first electrode is formed on the lower confinement layer and is spaced apart from the light emitting layer, the upper confinement layer, the contact layer, and the transparent electrode.

  • Publication number: 20050274947
    Abstract: The invention provides a TFT electrode structure and its manufacturing method that can prevent metal diffusion occurring in the fabrication of a TFT, and thereby reduce the risk of contamination of the chemical vapor deposition process due to metallic ion diffusion. The transparent pixel electrode is formed after the gate electrode metal so that the pixel transparent electrode can be used as a barrier layer to prevent metal diffusion under high temperature from the gate electrode metal to adjacent insulating layers or the active layer. Further, the method used to form the transparent pixel electrode is a low-temperature physical vapor deposition process, which affected less by the processing environment, and the transparent pixel electrode is a conductive layer that is not affected by metal diffusion.

  • Publication number: 20050274958
    Abstract: Disclosed is a buffer layer within a light emitting semiconducting device. The buffer layer comprises a plurality of metallic nitride layers sequentially formed on top of a sapphire substrate. In a fabrication process of the buffer layer, an Aluminum nitride layer is first formed on the sapphire substrate by a reaction with ammonia and the sapphire substrate's surface under a high temperature. Then on top of the Aluminum nitride layer, a plurality of metallic nitride layers are formed by reactions between ammonia and metallic organic materials under a high temperature. A buffer layer constructed as such has better quality and fewer defects.

  • Publication number: 20050048407
    Abstract: A method of manufacturing a TFT array panel for a LCD disclosers that the gate electrode wiring, transparent conducting electrode, and the first electrode of the storage capacity are formed while the first mask is processing. Then, the selective deposition method is used to process the growth of the first metal wiring. This, therefore, can reduce the numbers of the mask processes. Further, the metal deposition with photo-resist lift-off step is used to implement the layout of the second metal wiring for the consequent transmission lines in the manufacturing process. Finally, the process of the passivation layer deposition is used to implement associated circuits of a TFT array panel for a LCD. The TFT array panel for a LCD for manufacturing circuits can simplify the manufacturing process and reduce the cost.

  • Publication number: 20040178173
    Abstract: A method for laminating a material layer onto a transparent substrate. The method includes the steps of: providing a transparent substrate having an amorphous silicon layer formed thereon; forming an infrared absorbent metal layer on the material layer; inverting the material layer to laminate the metal layer onto the amorphous silicon layer; and exposing the metal layer and the amorphous silicon layer to infrared light to cause a metal silicide producing reaction and thus laminate the material layer and the transparent substrate.

  • Publication number: 20040180518
    Abstract: A method for forming a, single-crystal silicon layer on a transparent substrate. A transparent substrate having an amorphous silicon layer formed thereon and a silicon wafer having a hydrogen ion layer formed therein are provided. The silicon wafer is then reversed and laminated onto the amorphous silicon layer so that a layer of single-crystal silicon is between the hydrogen ion layer and the amorphous silicon layer. The laminated silicon wafer and the amorphous silicon layer are then subjected to laser or infrared light to cause chemical bonding of the single crystal silicon layer and the amorphous silicon layer and inducing a hydro-cracking reaction thereby separating the silicon wafer is and the transparent substrate at the hydrogen ion layer, and leaving the single-crystal silicon layer on the transparent substrate.
