Abstract
A solid-state imaging element with pixel transistors and wires capable of efficiently outputting and transferring a pixel signal from a stacked photoelectric conversion film while suppressing an increase in manufacturing cost, and a manufacturing method thereof are provided. There is provided a solid-state imaging element which includes a semiconductor substrate; a first photoelectric conversion unit provided on the semiconductor substrate; and a control unit provided stacked with the first photoelectric conversion unit and including a plurality of pixel transistors, in which the first photoelectric conversion unit includes a second electrode, a first photoelectric conversion film provided above the second electrode and converting light into charges, and a first electrode provided on the first photoelectric conversion film, the plurality of pixel transistors include an amplification transistor that amplifies and outputs the charges as a pixel signal, and a channel formation region of the amplification transistor made of an oxide semiconductor layer.
