  • Publication number: 20180240840
    Abstract: The present technology relates to a solid-state imaging apparatus and an electronic apparatus that makes it possible to improve coloration and improve image quality. The solid-state imaging apparatus is formed so that, in a pixel array unit in which combinations of a first pixel corresponding to a color component of a plurality of color components and a second pixel having higher sensitivity to incident light as compared with the first pixel are two-dimensionally arrayed, a first electrical barrier formed between a first photoelectric conversion unit and a first unnecessary electric charge drain unit in the first pixel, and a second electrical barrier formed between a second photoelectric conversion unit and a second unnecessary electric charge drain unit in the second pixel have different heights, respectively. The present technology can be applied to, for example, a CMOS image sensor.

  • Publication number: 20180234651
    Abstract: The present technology relates to a solid-state image sensor, an imaging device, and an electronic device capable of switching FD conversion efficiency in all pixels of a solid-state image sensor. A photodiode performs photoelectric conversion on incident light. A floating diffusion (FD) stores charge obtained by the photodiode. FD2, which is a second FD to which the capacity of an additional capacitor MIM is added, adds the capacity to the FD. The additional capacitor MIM is constituted by a first electrode formed by a wiring layer and a second electrode formed by a metallic light blocking film provided on a surface of a substrate on which the photodiode is formed. Switching between the FD and FD+FD2 allows switching of the FD conversion efficiency. The present technology is applicable to a CMOS image sensor.
