    Abstract: PROBLEM TO BE SOLVED: To provide a light emitting diode chip having an epitaxial semiconductor layer row equipped with an activity layer which emits electromagnetic radiation, and an electric contact structure which contains a radiation transparent and electric current extension layer comprising ZnO, and an electric connection layer, in which the loss by absorption in an electric connection region is reduced. SOLUTION: The current extension layer has a window where the connection layer is deposited on a covering layer of the semiconductor layer row. The connection layer is connected electrically with the current extension layer. The joint part of the connection layer and the covering layer is not connected electrically or is in bad conductive connection status during operation of the light emitting diode chip. All currents or almost all currents flow in the semiconductor layer row through the current extension layer. COPYRIGHT: (C)2004,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor light emitting device which is reduced in light absorption and improved in luminous efficiency. SOLUTION: A semiconductor light emitting device is equipped with a thin film laminate (12) which is provided with regions (40) which emit photons into active layers (22) and a front surface (16), and a rear surface (14) and connectors (26) and (32) formed on the front and rear of the thin film laminate (12) respectively so as to feed a current into the active layers (22). The regions (40) emitting photons are arranged as they are spatially separated from the connectors (26) and (32). By this setup, radiation absorbed by the connectors (26) and (32) can be reduced to an irreducible minimum. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To improve external effects of a semiconductor device by further reducing the absorption of light. SOLUTION: A thin film staple includes a light generation region and a light output coupling region. Photons are generated by recombination of charge carriers in the light generation region. In the light output coupling region, the light is coupled and then outputted from the semiconductor device. In this case, the light generation region and the light output coupling region are at least partially separated from each other on the surface of the thin film staple. COPYRIGHT: (C)2004,JPO
