摘要： A first P-type diffusion layer and a P-type semiconductor layer are provided on a silicon substrate, and two N-type diffusion layers are provided on a front surface of this P-type semiconductor layer to form two light receiving units. Three-layer translucent films, a first silicon oxide film, a silicon nitride film, and a second silicon oxide film are disposed on the N-type diffusion layers and on the P-type semiconductor layer between the two diffusion layers. Holes produced during a production process and distributed and captured in two interfaces between the three-layer translucent films can reduce a field intensity in the vicinity of the surface of the P-type semiconductor layer to below a conventional level and an inversion of a conductive type to reduce a leak current between the light receiving units accordingly.

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 includes a P type diffusion layer (101), a P type semiconductor layer (102), an N type diffusion layer (103) serving as a light receiving part, and a light transmitting film (104), all formed on a p type silicon substrate (100). The N type diffusion layer (103) has a thickness of 0.8 μm to 1.0 μm which is larger than an absorption length of incident light having wavelength of 400 nm, and such a concentration profile that a impurity concentration is not higher than 1E19 cm−3 on a surface and has a peak in a vicinity of the surface. Since recombination of carriers generated by the incident light is prevented in the vicinity of the surface of the N type diffusion layer (103), sensitivity of the light receiving device is enhanced and response speed is increased by the low-resistance N type diffusion layer (103) having a larger junction depth.
