摘要 | PURPOSE:To correctly control width of a ridge and thickness of a clad layer to improve manufacturing yield and device characteristics by forming a stripe ridge by means of selective growth. CONSTITUTION:An n-In0.5(Ga0.3Al0.7)0.5P clad layer 11, an In0.5Ga0.5P active layer 12 and a p-In0.5(Ga0.3Al0.7)0.5P clad layer 13 are formed on an N-GaAs substrate 10. A mask 19 having a stripe opening is formed on the layer 13. A p-In0.5(Ga0.3Al0.7)0.5P layer is selectively grown on an exposed part of the layer 13 to form a stripe p-InGaAlP ridge 14. A p-In0.5Ga0.5P easily-power- supplied layer 15 is formed on it. After the mask is removed, a p-GaAs contact layer 16 is formed. A p-side electrode 17 is formed on the layer 16 while an n-side electrode is formed on the substrate 10 side to obtain HBB semiconductor laser. |
其他摘要 | 用途:通过选择性生长形成条纹脊,正确控制脊的宽度和包层的厚度,以提高制造产量和器件特性。组成:n-In0.5(Ga0.3Al0.7)0.5P包层11,In0.5Ga0.5P有源层12和p-In0.5(Ga0.3Al0.7)0.5P包层13在层13上形成具有条形开口的掩模19.在层13的暴露部分上选择性地生长p-In0.5(Ga0.3Al0.7)0.5P层。形成条纹p-InGaAlP脊14.在其上形成p-In0.5Ga0.5P易供电层15。在去除掩模之后,形成p-GaAs接触层16。在层16上形成p侧电极17,同时在基板10侧形成n侧电极,以获得HBB半导体激光器。 |
