    • PURPOSE: A semiconductor light emitting device and a method for manufacturing the device are provided for enlarging the lifecycle of the semiconductor light emitting device using nitride chemicals of third thru fifth families. CONSTITUTION: A semiconductor light emitting device using nitride chemicals of third thru fifth families includes first and second clad layers(5,7), an activation layer(6), a stripe(8), and a burial layer(9). The first clad layer(5) is of a first conduction type. The activation layer(6) is formed on the first clad layer(5). The second clad layer(7) of a second conduction type is formed on the activation layer(6). The stripe is formed on the second clad layer(7). The burial layer(9) buries an opposite side of the stripe(8). The burial layer(9) is formed by removing the burial layer(9) selectively on the stripe(8) by etching the burial layer(9) using a mask on the stripe(8) as an etching stopper, after developing the burial layer(9) on the second clad layer(7) non-selectively with the mask existing on the stripe(8).
    • 目的:提供半导体发光器件和该器件的制造方法,用于使用第三至第五族的氮化物化学品扩大半导体发光器件的寿命。 构成:使用第三至第五族的氮化物的半导体发光器件包括第一和第二覆盖层(5,7),激活层(6),条纹(8)和埋藏层(9)。 第一包层(5)是第一导电类型。 活化层(6)形成在第一包层(5)上。 在激活层(6)上形成第二导电类型的第二覆层(7)。 条纹形成在第二包覆层(7)上。 埋置层(9)埋在条纹(8)的相对侧。 通过在显影埋藏层之后,使用在条纹(8)上的掩模作为蚀刻阻挡层蚀刻埋藏层(9),通过在条纹(8)上选择性地去除掩埋层(9)而形成埋藏层(9) (9)在所述条纹(8)上存在的掩模非选择性地在所述第二包层(7)上。

    • PURPOSE: A semiconductor laser and a method for manufacturing the same are provided to stably control a transverse mode and prevent a high order mode oscillation upon a high output power. CONSTITUTION: A semiconductor laser is made of nitride III-V compound semiconductor sand has a ridge-shaped stripe. Opposite sides of the ridge are buried by a buried semiconductor layer such as AlGaN buried layer made of a nitride III-V compound semiconductor at least of which is a non-single crystal such as polycrystal. The buried semiconductor layer is grown under a growth temperature in the range from 520°C to 760°C. And the difference in refractive index between the ridge portion and the buried semiconductor layer is readily controlled to prevent high order mode oscillation. Since the entirety of the ridge be buried with good smoothness, heat dissipation from the ridge portion is improved, deterioration of the active layer is prevented.
    • 目的:提供一种半导体激光器及其制造方法,以稳定地控制横向模式并防止高输出功率下的高阶振荡。 构成:半导体激光器由氮化物III-V化合物半导体砂制成,具有脊状条纹。 脊的相对侧被诸如由氮化物III-V化合物半导体制成的AlGaN掩埋层的掩埋半导体层掩埋,其中至少一个是诸如多晶的非单晶。 埋置的半导体层在520℃至760℃的生长温度下生长。 并且容易控制脊部与掩埋半导体层之间的折射率差异,以防止高阶振荡。 由于脊的整体以良好的平滑度被掩埋,所以从脊部散热得到改善,有效层的劣化被防止。
