Image pickup device and electronic apparatus

摘要

An image pickup device includes on a silicon layer: a photodiode provided on each pixel basis to perform photoelectric conversion to generate a charge depending on the light receiving amount; a floating diffusion section configured to store the charge generated by the photodiode; and a transistor configured to output a pixel signal at a voltage in accordance with a level of the charge stored in the floating diffusion section, wherein the image pickup device further includes a hermetically-sealed cavity section inside the silicon layer and on at least one of the underside of the floating diffusion section and the underside of a channel body region of the transistor.
