摘要： A semiconductor light emitting device is fabricated by forming a mask having an opening on a substrate, forming a crystal layer having a tilt crystal plane tilted from the principal plane of the substrate by selective growth from the opening of the mask, and forming, on the crystal layer, a first conductive type layer, an active layer, and a second conductive type layer, which extend within planes parallel to the tilt crystal plane, and removing the mask. The semiconductor light emitting device can be fabricated without increasing fabrication steps while suppressing threading dislocations extending from the substrate side and keeping a desirable crystallinity. The semiconductor light emitting device is also advantageous in that since deposition of polycrystal on the mask is eliminated, an electrode can be easily formed, and that the device structure can be finely cut into chips.

摘要： A semiconductor light-emitting element is provided which has a structure that does not complicate a fabrication process, can be formed in high precision and does not invite any degradation of crystallinity. A light-emitting element is formed, which includes a selective crystal growth layer formed by selectively growing a compound semiconductor of a Wurtzite type, a clad layer of a first conduction type, an active layer and a clad layer of a second conduction type, which are formed on the selective crystal growth layer wherein the active layer is formed so that the active layer extends in parallel to different crystal planes, the active layer is larger in size than a diffusion length of a constituent atom of a mixed crystal, or the active layer has a difference in at least one of a composition and a thickness thereof, thereby forming the active layer having a number of light-emitting wavelength regions whose emission wavelengths differ from one another. The element is so arranged that an electric current or currents are chargeable into the number of light-emitting wavelength regions. Because of the structure based on the selective growth, the band gap energy varies within the same active layer, thereby forming an element or device in high precision without complicating a fabrication process.
