ABSTRACT:
A light receiving element is comprised of a light sensitive surface on a semiconductor substrate and a positive electrode (anode), a negative electrode (cathode), a mounting precision test mask, a conductive electrode wire, and solder resist on the same substrate surface. A metal thin film, a mounting alignment mark, and a mounting precision mark window are provided on the back side of the substrate. Two or more electrode surfaces having either the anode or the cathode used as the common electrode are provided. The light sensitive surface is positioned approximately in the center between these two electrode surfaces. A highly precise mounting can therefore be achieved with the solder bump, even when mounting single light receiving elements. High precision mounting is also obtained when mounting light receiving element arrays. This type of light receiving element can be precisely positioned and bonded by solder bumps to a substrate having an optical fiber fitted in the V groove.
