  • Publication number: 20160231468
    Abstract: The present technology relates to a lens array and a manufacturing method therefor, a solid-state imaging apparatus, and an electronic apparatus that can improve the AF performance while suppressing the deterioration of image quality. A lens array includes microlenses that are formed corresponding to phase difference detection pixels that are provided to be mixed in imaging pixels. Each of the microlenses is formed such that a lens surface thereof is a substantially spherical surface, the microlens has a rectangular shape in a planar view and four corners are not substantially rounded, and a bottom surface in vicinity of an opposite-side boundary portion that includes an opposite-side center portion of a pixel boundary portion in a cross-sectional view is higher than a bottom surface in vicinity of a diagonal boundary portion that includes a diagonal boundary portion. The present technology is applicable to a lens array of a CMOS image sensor, for example.

  • Publication number: 20160104736
    Abstract: A solid-state imaging device includes: a photodiode formed to be segmented with respect to each pixel in a pixel area in which plural pixels are integrated on a light receiving surface of a semiconductor substrate; an insulator film formed on the semiconductor substrate to cover the photodiode; a recessed part formed with respect to each of the pixels in the insulator film in an upper part of the photodiode; a first light transmission layer of a siloxane resin formed to fill the recessed part and configure an optical waveguide in the pixel area; a second light transmission layer formed to configure an on-chip lens with respect to each of the pixels in the pixel area; and a guard ring formed to surround an outer circumference of the pixel area to partition an inner area containing the pixel area and an outer dicing area.

  • Patent number: 6383941
    Abstract: The present disclosure relates to semiconductor processing, and to the plasma etching of organic layers, and in particular antireflective coating layers. We have discovered a particular combination of gases useful in producing chemically reactive plasma species, which provides unexpected control over etched feature critical dimension, etch profile, and uniformity of etch across a substrate surface, despite a difference in the spacing of etched features over the substrate surface. The combination of gases which produces chemically reactive plasma species consists essentially of CxHyFz, a bromine-comprising compound (which is typically HBr), and O2, where x ranges from 1 to 4, y ranges from 0 to 3, and z ranges from 1 to 10. Oxygen atoms may be substituted for hydrogen atoms in the CxHyFz compound to a limited extent Essentially inert gases which do not produce chemically reactive species may be added to the combination of etchant-species producing gases.
