Zusammenfassung: | A semiconductor light-receiving element includes a substrate; a light-receiving mesa portion, formed on top of the substrate, including a first semiconductor layer of a first conductivity type, an absorption layer, and a second semiconductor layer of a second conductivity type; a light-receiving portion electrode, formed above the light-receiving mesa portion, connected to the first semiconductorlayer; a pad electrode formed on top of the substrate; and a bridge electrode, placed so that an insulating gap is interposed between the bridge electrode and the second semiconductor layer, configured to connect the light-receiving portion electrode and the pad electrode on top of the substrate, the bridge electrode being formed in a layer separate from layers of the light-receiving portion electrode and the pad electrode.
一种半导体光接收元件包括基板;光接收台面部分,形成在基板的顶部上,包括第一导电类型的第一半导体层、吸收层和第二导电类型的第二半导体层;光接收部分电极,形成在光接收台面部分上方,连接到第一半导体层;衬垫电极,其形成在基板的顶部上;以及桥接电极,其被放置成使得绝缘间隙介于桥接电极和第二半导体层之间,被构造为将光接收部分电极和在基板的顶部上的衬垫电极连接,该桥接电极形成在与衬垫电极和光接收部分电极 |
