  • Patent number: 9601533
    Abstract: A method of manufacturing a solid-state imaging apparatus, comprising preparing a semiconductor substrate including a photoelectric conversion portion and a structure which includes an insulating member formed on the photoelectric conversion portion and a wiring pattern formed in the insulating member, forming a film made of SiC and/or SiCN on the structure, forming an opening immediately above the photoelectric conversion portion by removing part of the film and part of the insulating member, and depositing a member in the opening and on the film, and forming a light-guide portion by polishing the member so as to expose the film.
    Type: Grant
    Filed: June 3, 2014
    Date of Patent: March 21, 2017
    Assignee: Canon Kabushiki Kaisha

  • Patent number: 9466639
    Abstract: A method of manufacturing a solid-state imaging apparatus, comprising preparing a substrate on which photoelectric conversion portions are arranged, forming inner lenses corresponding to the photoelectric conversion portions, and forming microlenses corresponding to the photoelectric conversion portions, wherein the forming inner lenses includes forming, on the substrate, a dielectric film for forming the plurality of inner lenses, and etching second portions of the dielectric film around first portions serving as central portions of the inner lenses while leaving upper faces of the first portions, so as to form curved faces or inclined faces connected to the upper faces.

  • Patent number: 8852987
    Abstract: A method of manufacturing an image pickup device includes a step of forming a filling member such that the filling member covers a light guiding part and a peripheral part provided in a film. The light guiding part is positioned on an image pickup region of the image pickup device and has openings that correspond to respective photoelectric conversion portions. The peripheral part is positioned on a peripheral region of the image pickup device. The filling member fills in the openings. The method includes a step of processing the filling member. The method includes a step of forming light guiding members, which is performed after the step of processing filling member has been performed, by a polishing process performed on the filling member so that the light guiding part is exposed. The light guiding members are part of the filling member and disposed in the openings.
