摘要： An imaging device includes a photoelectric converter, a charge holding section that is provided on a side of the photoelectric converter opposite to a light entrance side of the photoelectric converter and holds a signal charge generated by the photoelectric converter, and a light shielding section that has a first light shielding surface extending toward the charge holding section from between the charge holding section and the photoelectric converter.

摘要： There are provided a solid-state imaging device and an electronic apparatus that can enhance the conversion efficiency to a degree similar to that of a non-sharing pixel and can maintain the optical symmetry also in a case where sharing between pixels is performed. The solid-state imaging device includes a plurality of pixels arranged in a matrix, and each of the plurality of pixels includes: a photoelectric conversion unit configured to photoelectrically convert incident light; a floating diffusion portion in which signal charge generated by the photoelectric conversion unit is stored; an amplification transistor configured to amplify a potential corresponding to an amount the signal charge stored in the floating diffusion portion, and output a pixel signal corresponding to the amplified potential; and a conversion-efficiency adjustment transistor configured to adjust a conversion efficiency of the signal charge stored in the floating diffusion portion. At least a part of the plurality of pixels forms sharing pixels, and a transistor other than the amplification transistor and the conversion-efficiency adjustment transistor is shared by a plurality of pixels forming the sharing pixels.
