Abstract

PURPOSE:To exactly approach an optical fiber to a semiconductor light receiving element and easily position therebetween by forming a recess on the contacting surface of the optical fiber with the element formed with P-N junction and inserting the optical fiber at the end into the recess. CONSTITUTION:An N-type region and a guard ring 9 are formed to extend an operating depletion layer at the center on the back surface of a P-type Si substrate 8, an aluminum electrode 10 is mounted on the N-type region, and an oxide film 11 is coated on the periphery thereof. Then, a recess 12 for inserting an optical fiber 4 is formed at the portion confronting the N-type region on the surface of the substrate 8, a P<+>-type layer 13 is diffused on the surface including the recess 12, and an aluminum electrode 14 is coated on the periphery of the recess 12. In this manner a light receiving element 1 is formed, the N-type region is confronted with the conductive layer 16 formed on a ceramic substrate 15, and epoxy adhesive region 17 is filled in the space thereamong fixedly. Thereafter, they are connected as predetermined, an optical fiber 4 is inserted into the recess 12 on the surface of the element 1 with a transparent resin 22, and the periphery of the fiber 4 is molded with resin 24.
