摘要 | PURPOSE:To improve the adhesion between a substrate and an electrode in a semiconductor laser element by forming the surface of an Au electrode on an anode oxide film becoming an insulating film in flat and smooth state without rugged state. CONSTITUTION:A buffer layer 2, an active layer 3 and a top layer 4 are formed by liquid phase epitaxial process on a PbTe substrate Thereafter, the substrate is mesa etched in predetermined size, the contact portion A between the substrate and the electrode is then removed to form an anode oxide film 7 on the surface of the substrate. Then, the substrate formed with the film 7 is heated in nitrogen or argon gas atmosphere of high purity. In this manner, the anode oxide film 7 becomes dense. |
其他摘要 | 用途:通过在阳极氧化膜上形成Au电极的表面,使其成为平坦和平滑状态的绝缘膜而没有粗糙状态,从而改善半导体激光器元件中基板和电极之间的粘附性。组成:缓冲层2,活性层3和顶层4通过液相外延工艺在PbTe衬底1上形成。此后,基板被预定尺寸的台面蚀刻,基板和电极之间的接触部分A然后除去,在基板表面上形成阳极氧化膜7。然后,将形成有膜7的基板在高纯度的氮气或氩气气氛中加热。以这种方式,阳极氧化膜7变得致密。 |
