  • Patent number: 8743265
    Abstract: A solid-state imaging device includes a pixel that has a photoelectric conversion section which converts incident light into an electric signal; a color filter which is formed corresponding to the pixel; a micro lens which focuses the incident light to the photoelectric conversion section via the color filter; and an in-layer lens which is formed between the color filter and the micro lens and has a refractive index smaller than that of the micro lens.

  • Publication number: 20120235266
    Abstract: There is provided a solid-state imaging device including plural pixel regions, each including a pixel having a photoelectric conversion unit, a color filter, and a microlens that condenses the incident light to the photoelectric conversion unit; a first light shielding portion that has a first end face at the side of the microlens, and a second end face opposite to the first end face, and that is formed at each side portion of each pixel region of the plurality of the pixel regions; and a second light shielding portion that has a first end face at the side of the microlens, and a second end face opposite to the first end face, and that is formed at each corner portion of the pixel region, in which a distance from a surface of the pixel to the first end face is short compared to the first light shielding portion.

  • Publication number: 20070287087
    Abstract: The present invention provides a colored photosensitive resin composition which causes a small change in exposure when a pattern is subjected to projection exposure. Disclosed is a colored photosensitive resin composition comprising a dye, a photo acid generator, a curing agent, an alkali-soluble resin, a solvent, and a compound represented by the formula (I): in the formula (I), R1 to R3 each independently represents a hydrogen atom, a linear alkyl group having 1 to 6 carbon atoms, a branched alkyl group having 3 to 12 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms or an aryl group having 6 to 12 carbon atoms, and a hydrogen atom on the linear alkyl group having 1 to 6 carbon atoms, a hydrogen atom on the branched alkyl group having 3 to 12 carbon atoms, a hydrogen atom on the cycloalkyl group and a hydrogen atom on the aryl group may be substituted with a hydroxyl group, provided that at least one of R1 to R3 represents a group other than a hydrogen atom.
