  • Publication number: 20240163587
    Abstract: To prevent a decrease in a saturation charge when a phase difference signal is generated. A pixel includes a plurality of photoelectric conversion sections that is formed on a semiconductor substrate and performs photoelectric conversion of incident light from a subject to generate a charge. An intra-pixel separator separates the plurality of photoelectric conversion sections. An overflow path in the intra-pixel separator transfers charges overflowed in the plurality of photoelectric conversion sections to each other. An overflow gate in the pixel and adjusts a potential of the overflow path. A pixel separator is disposed at a boundary between the pixels. A charge holding section holds the generated charge. A charge transfer section is disposed one-by-one for the plurality of photoelectric conversion sections and transfers the generated charge to the charge holding section. An image signal generating section generates an image signal on the basis of the generated charge.

  • Patent number: 11329078
    Abstract: Disclosed is a solid-state imaging device including a plurality of pixels and a plurality of on-chip lenses. The plurality of pixels are arranged in a matrix pattern. Each of the pixels has a photoelectric conversion portion configured to photoelectrically convert light incident from a rear surface side of a semiconductor substrate. The plurality of on-chip lenses are arranged for every other pixel. The on-chip lenses are larger in size than the pixels. Each of color filters at the pixels where the on-chip lenses are present has a cross-sectional shape whose upper side close to the on-chip lens is the same in width as the on-chip lens and whose lower side close to the photoelectric conversion portion is shorter than the upper side.
