| 20090001408 | Method for forming a semiconductor light-emitting device and a semiconductor light-emitting device - A semiconductor light-emitting device with a new layer structure is disclosed, where the current leaking path is not caused to enhance the current injection efficiency within the active layer. The device provides a mesa structure containing active layer and a p-type lower cladding layer on a p-type substrate and a burying layer doped with iron (Fe) to bury the mesa structure, where the burying layer shows a semi-insulating characteristic. The device also provides an n-type blocking layer arranged so as to cover at least a portion of the p-type buffer lower within the mesa structure. The n-type blocking layer prevents the current leaking from the burying layer to the p-type buffer layer, and the semi-insulating burying layer that covers the rest portion of the mesa structure not covered by the n-type blocking layer prevents the current leaking from the n-type blocking layer to the n-type cladding layer within the mesa structure. | 01-01-2009 |
| 20090086779 | SEMICONDUCTOR LASER DIODE WITH REDUCED PARASITIC CAPACITANCE - The LD of the invention provides a semiconductor stack including the current confinement region with the active mesa and the semi-insulating burying regions putting the active mesa therebeteen and the conductive region in contiguity with the current confinement region. The current confinement region and the conductive region are provided on epitaxially grown cladding layer. Two semiconductor regions, which are physically isolated to each other and each includes the semiconductor substrate, are provided on the semiconductor stack. One of regions comes in contact with one of burying regions and the active mesa, while, the other semiconductor regions comes in contact with the other of burying regions and the conductive region. | 04-02-2009 |
