  • Publication number: 20150102442
    Abstract: A solid-state imaging device comprises an imaging pixel located in a light receiving region, the imaging pixel being a component of a unit pixel that is one of a plurality of unit pixels arranged in an array direction. A phase difference detection pixel is located in the light receiving region and is a component of the unit pixel, and has a corresponding photodiode with an upper surface. A first microlens corresponds to the imaging pixel, and a second microlens corresponding to the phase difference detection pixel. The second microlens has a first bottom surface in the array direction and a second bottom surface in a direction diagonal to the array direction, the second bottom surface being closer to the upper surface of the photodiode than the first bottom surface.
