Abstract:
1. A semiconductor light receiving device, comprising: a semiconductor substrate; a semiconductor layer which is laminated on the semiconductor substrate and includes an upper surface portion; a reflecting film which is formed to cover the upper surface portion of the semiconductor layer and which has at least one through hole being configured to form in the reflecting film a discontinuous loop, the reflecting film including a principal reflecting region and a peripheral reflecting region surrounding the principal reflecting region; and an upper electrode which is formed to cover at least a portion of an upper surface of the reflecting film and includes a junction portion extending through the at least one through hole of the reflecting film to be provided in contact with the upper surface portion of the semiconductor layer, the junction portion of the upper electrode surrounding only a portion of a circumference of the principal reflecting region of the reflecting film, the principal reflecting region being connected to the peripheral reflecting region which is located outside the junction portion, wherein the semiconductor light receiving device detects light entering from a side of the semiconductor substrate which is opposed to the semiconductor layer.
