    摘要: A light receiving device includes a silicon substrate, a first P type diffusion layer on the silicon substrate, and a P type semiconductor layer on the P type diffusion layer. On a surface part of the P type semiconductor layer, two N type diffusion layers as light receiving parts, and a second P type diffusion layer between the two N type diffusion layers are provided. On the P type semiconductor layer, an antireflection film structure composed of a first silicon oxide formed by thermal oxidation and a second silicon oxide formed by CVD is provided. A film thickness of the first silicon oxide is set at about 15 nm, thus a defect in a interface between the first silicon oxide and the P type semiconductor layer is prevented. A film thickness of the second silicon oxide is set at about 100 nm, thus a leak current between cathodes is prevented when a power supply voltage is applied for long period of time.

    摘要: A light receiving device 12 that receives reflected light condensed by a light receiving condenser means 14 has two first and second electrodes 15, 16 provided on a light receiving surface at prescribed intervals along a baseline that connects a light emitting device 11 with the light receiving device and a resistive region 21 provided between the two electrodes. An electric charge generated at the incident position of light incident on the light receiving surface of the light receiving device 12 becomes a photo current and outputted from the first and second electrodes 15, 16 via the resistive region 21. The resistance value of the resistive region 21 of the light receiving device 12 is distributed so as to be roughly inversely proportional to a distance from the optical axis of the light receiving condenser means 14 to the incident position of a light spot on the light receiving surface.
