PHOTO SEMICONDUCTOR DEVICE

摘要

PURPOSE:To easily couple optical fibers in a photo semiconductor device by employing a transparent insulator layer and an active semiconductor layer laminated on a substrate and forming a hole for inserting the optical fibers reaching the insulator layer from the back surface of the substrate at the opposed position with the element region in the active layer. CONSTITUTION:A photo semiconductor element 2 is secured with solder 11 to the bottom surface in the body of a container 1 at the substrate 21 side, and so installed as to communicate with an optical fiber inserting hole 12 perforated at the bottom of the body with a hole 25 for inserting the optical fiber formed on the back of the element 2 at its secured position. The optical fibers 3 inserted into the holes 12, 25 are secured to the bottom of the container with adhesive resin 31.
