易扩展的集成式光电耦合器及其制作方法
摘要：
本发明公开了一种易扩展的集成式光电耦合器，所述集成式光电耦合器由LED发光器件和硅基光敏二极管组成；所述硅基光敏二极管的光敏区表面设置有光耦合介质层，光敏区边沿的光耦合介质层表面设置有金属布线层，光敏区中部的光耦合介质层表面设置有金属焊盘，金属焊盘和金属布线层之间通过一窄条形的连接金属层连接，连接金属层设置于光耦合介质层表面；所述金属焊盘与位于LED发光器件上发光区中部的LED阳极焊接固定。本发明的有益技术效果是：提出了一种新结构的光电耦合器，该光电耦合器的光传输结构的尺寸十分小，器件在相应方向上的物理尺寸也大幅缩减。
摘要（英）：

The invention discloses an expandable integrated photoelectric coupler. The integrated photoelectric coupler is composed of an LED and a silica-based support photosensitive diode. An optical coupling dielectric layer is arranged on the surface of a photosensitive area of the silica-based support photosensitive diode. A metal wiring layer is arranged on the surface of the optical coupling dielectric layer on the edge of the photosensitive area. A metal bonding pad is arranged on the surface of the optical coupling dielectric layer of the middle of the photosensitive area. The metal bonding pad and the metal wiring layer are connected through a narrow-strip-shaped connection metal layer. The connection metal layer is arranged on the surface of the optical coupling dielectric layer. The metal bonding pad is fixed and welded to an LED anode of the middle of a light-emitting region on the LED. The integrated photoelectric coupler has the advantages that the photoelectric coupler is of a novel structure, the size of the optical transmission structure of the photoelectric coupler is quite small, and the physical size of the device in the corresponding direction is greatly decreased.
