  • Publication number: 20130200419
    Abstract: A semiconductor light emitting component including an epitaxial structure, a first electrode, a second electrode, a first cutout structure and a second cutout structure is provided. The epitaxial structure includes a first type doped layer, a light emitting portion and a second type doped layer. The first electrode is formed on a surface of the first type doped layer. The second electrode is formed on a surface of the second type doped layer. The first cutout structure is formed in the first type doped layer to expose at least a portion of the first electrode. The second cutout structure is formed in the first type doped layer, the light emitting portion and the second type doped layer so as to expose at least a portion of the second electrode.

  • Publication number: 20130175553
    Abstract: The present invention is directed to a light-emitting diode (LED) device, which includes at least one LED unit. Each LED unit includes at least one LED, which includes a first doped layer, a second doped layer and a conductive defect layer. The conductive defect layer is formed on the first or second doped layer. The conductive defect layer may be deposited between two LEDs, or between the first/second doped layer and an electrode.

  • Publication number: 20130178046
    Abstract: A method of manufacturing a semiconductor apparatus is disclosed. A first-type doped layer, a second-type doped layer, and an internal electrical connection layer are formed. The internal electrical connection layer is deposited and electrically coupled between the first-type doped layer and the second-type doped layer. In one embodiment, the internal electrical connection layer is formed by using a group IV based precursor and nitrogen based precursor. In another embodiment, the internal electrical connection layer is formed by a mixture comprising a carbon-contained doping source, and the internal electrical connection layer has a carbon concentration greater than 1017 atoms/cm3. In a further embodiment, the internal electrical connection layer is formed at a temperature lower than those of the first-type doped layer and the second-type doped layer.

  • Publication number: 20130175674
    Abstract: A semiconductor apparatus includes a p-type doped layer, an n-type doped layer, and an internal electrical connection layer that is deposited and electrically coupled between the p-type doped layer and the n-type doped layer. In one embodiment, the internal electrical connection layer includes a group IV element and a nitrogen element, and the number of atoms of the group IV element and the nitrogen element is greater than 50% of the total number of atoms in the internal electrical connection layer. In another embodiment, the internal electrical connection layer includes carbon element with a concentration greater than 1017 atoms/cm3. In a further embodiment, the internal electrical connection layer is formed at a temperature lower than those of the p-type doped layer and the n-type doped layer.
