摘要 | PURPOSE:To contrive to improve the reliability by preventing the deterioration in element characteristics by a method wherein an electrode is formed by a coat of Ti layer on a semiconductor contact layer, next a coat or more of Pt layer and Ti layer in this order, and successive coats of Pt layer and Au layer thereon. CONSTITUTION:As the p-electrode, using electron beam deposition, the contact layer 6 is coated first with a Ti layer 7 and next with Ti-layers/Pt-layers by five-time repetition in this order, resulting in the formation of an intermediate multilayer structure 11; finally, it is coated with a Pt-layer 8, which is then coated with an Au layer 9 by a normal electrolytic plating. Thereafter, heat treatment is carried out to take ohmic contact between the contact layer 6 and the Ti layer 7. Next, after adhesion of an Au-Ge-Ni layer 10 as the n- electrode, ohmic contact is taken by forming an alloy layer on heat treatment. Then, the resonator is formed by cleavage in the direction parallel with the drawing. |
其他摘要 | 目的:通过一种方法防止元件特性恶化来提高可靠性,其中通过在半导体接触层上涂覆Ti层形成电极,然后依次涂覆Pt层和Ti层或更多层,在其上连续涂覆Pt层和Au层。组成:作为p电极,使用电子束沉积,接触层6首先涂有Ti层7,接着涂有Ti层/ Pt层,按此顺序重复五次,导致形成中间多层结构11;最后,涂覆Pt层8,然后通过常规电解电镀涂覆Au层9。之后,进行热处理以使接触层6与Ti层7之间形成欧姆接触。接着,在粘附作为n电极的Au-Ge-Ni层10之后,通过形成合金层来进行欧姆接触。热处理。然后,通过在与图平行的方向上的解理形成谐振器。 |
