  • Patent number: 7259791
    Abstract: In a solid-state image pickup device including a light receiving sensor portion in a surface layer portion of a substrate, an in-layer lens disposed above the light receiving sensor portion, a color filter disposed on the in-layer lens, and an interlayer film disposed below the in-layer lens, an antireflection film is formed between the in-layer lens and the color filter, the antireflection film being formed of material having a refractive index which is an intermediate value between the refractive index of the in-layer lens and the refractive index of the color filter. Further, another antireflection film is formed between the in-layer lens and the interlayer film, the other antireflection film being formed of material having a refractive index which is an intermediate value between the refractive index of the in-layer lens and the refractive index of the interlayer film.

  • Patent number: 6069350
    Abstract: In a solid state imaging device having light receiving sections arranged in horizontal and vertical directions with different pitches, an on-chip micro-lens having a focusing efficiency optimized in both horizontal and vertical directions is formed. The solid state imaging device comprises a plurality of light receiving sections (42) arranged in horizontal and vertical directions with different pitches, a foundation layer (47) formed over the light receiving sections (42) and having convex portions on portions between the light receiving sections (42) in a fine pitch direction and having concave portions at least along a straight line connecting centers of the light receiving sections in a coarse pitch direction, and a plurality of lenses (48) formed on the concave portions so as to at least partially overlap on the convex portions in correspondence with the light receiving sections (42).

  • Patent number: 5986704
    Abstract: The displacement amount of a color filter which is displaced with respect to an opening of a light-shielding film along the surface of a substrate increases as the distance from the substantial center of an image pickup region to the opening of the light-shielding film increases, and the height from the surface of the substrate to the substantial center in the direction of thickness of the color filter increases. For this reason, whole light incident on the sensor of each pixel can pass through only a corresponding color filter and also pass through the entire thickness of the color filter. Even when the thickness or height of the color filter changes in units of pixels, a high-quality image having no color irregularity can be obtained.

  • Patent number: 5736756
    Abstract: A solid-state image sensing device including a light shielding film of aluminum or the like formed to make contact with a silicon substrate over a sensor region so that no insulating film is present between the substrate and the light shielding film in the periphery of an opening of the sensor region. The solid-state image sensing device further includes a potential applying device for applying a predetermined potential to the light shielding film. Accordingly, the solid-state image sensing device can reduce the smear due to the leakage of incident light through between the substrate and the light shielding film in the periphery of the opening of the sensor region and improve the photodetecting characteristics of the sensor region.

  • Patent number: 5581099
    Abstract: In a CCD solid state image sensing device in which a photosensitive section is constructed by a photodiode formed by a PN junction between a first P-type well region and an N-type impurity diffusion region formed on an N-type silicon substrate, the N-type impurity diffusion region is formed by the ion implantation of single substance of arsenic (As). According to this CCD solid state image sensing device, a bright flaw on an image sensing screen, which is one of the defects encountered with an image sensing screen, can be reduced. Also, the n-type impurity diffusion region constructing the PN Junction can be reduced in size and the CCD solid state image sensing device itself can be made compact in size. Further, a method of manufacturing a CCD solid state image sensing device also is provided.
