    摘要: In order to remove the problems in conventional nitride compound semiconductor laser structures, namely, high operation voltage caused by a high resistance in a p-type layer and a high contact resistance of an electrode, damage to the crystal caused by dry etching, insufficient current injection, and the need for a high current density, a nitride compound semiconductor light emitting device has current blocking layers made of n-type B(1−x−y−z)InxAlyGazN (0≦x≦1, 0≦y≦1, 0≦z≦1) single crystal containing an oxide of a predetermined metal, carbon and impurities exhibiting p-type and n-type conductivity, or i-type B(1−x−y−z)InxAlyGazN (0≦x≦1, 0≦y≦1, 0≦z≦1) single crystal in which carriers are inactivated by hydrogen or oxygen to realize an internal current blocking structure without the need for dry etching. By applying a reverse bias voltage, the semiconductor can be activated only along a current path, and the remainder region is utilized as a current blocking layer. When the n-side electrode has a unique three-layered structure, a reduction in contact resistance and good wire bonding are promised.

    摘要: Disclosed is a gallium nitride-based compound semiconductor device, including a laminate film consisting of a plurality of layers stacked one upon the other to form a pn-junction and formed of InGaAlN. The semiconductor device also includes an n-side electrode and a p-side electrode to supply current to the pn-junction. Further included is a heat generation structure formed within the laminate film. The heat generation structure includes a low resistivity portion having a relatively low resistivity and a high resistivity portion having a relatively high resistivity and positioned adjacent to the low resistivity portion. The low resistivity portion and the high resistivity portion are formed within a single layer, differ from each other in carrier concentration, and formed by introducing an impurity into the single layer in a different dose such that the low resistivity portion is positioned closer to the p-side electrode than the high resistivity portion.
