  • Patent number: 10062723
    Abstract: A semiconductor device is reduced in power consumption, the semiconductor device including a solid-state imaging device that includes pixels each having a plurality of light receiving elements. A pixel having first and second photodiodes is provided with a first transfer transistor that transfers charge in the first photodiode to a floating diffusion capacitance section, and a second transfer transistor that combines charge in the first photodiode and charge in the second photodiode, and transfers the combined charge to the floating diffusion capacitance section. Consequently, the semiconductor device is reduced in power required for activation of each transfer transistor in operation such as imaging with the solid-state imaging device.

  • Patent number: 9893109
    Abstract: In a solid state image sensor which has two photodiodes juxtaposed in a predetermined direction in each pixel and is formed by carrying out divided exposure, that is, exposure treatment of an entire chip by a plurality of times of exposure, image quality is improved and autofocusing speed is increased. Provided is a solid state image sensor having a first exposure region having a first region and a second exposure region having a second region. They overlap with each other in a third region between the first and second regions. In a pixel formed in the third region, a photodiode formed through a mask for first exposure region is placed at a position closer to the side of the second region than another photodiode formed through a mask for second exposure region is.

  • Publication number: 20170373112
    Abstract: In a solid-state imaging device including a plurality of pixels each pixel including a plurality of photodiodes, it is prevented that an incidence angle of incident light on the solid-state imaging device becomes large in a pixel in an end of the solid-state imaging device, causing a difference in output between the two photodiodes in the pixel, and thus autofocus detection accuracy is deteriorated. Photodiodes extending in a longitudinal direction of a pixel allay section are provided in each pixel. The photodiodes in the pixel are arranged in a direction orthogonal to the longitudinal direction of the pixel allay section.
