Abstract:
It is possible to curb noise, color mixing, and the like. An imaging apparatus includes: a semiconductor; a photoelectric conversion unit that is provided on the semiconductor substrate and generates electrical charge in accordance with the amount of received light through photoelectric conversion; an electrical charge holding unit that is disposed on a side closer to a first surface of the semiconductor substrate than the photoelectric conversion unit and holds the electrical charge transferred from the photoelectric conversion unit; an electrical charge transfer unit that transfers the electrical charge from the photoelectric conversion unit to the electrical charge holding unit; a vertical electrode that transmits the electrical charge generated by the photoelectric conversion unit to the electrical charge transfer unit and is disposed in a depth direction of the semiconductor substrate, and a first light control unit that is disposed on a side closer to a second surface that is a side opposite to the first surface of the semiconductor substrate than the vertical electrode, is disposed at a position overlapping the vertical electrode in a plan view of the semiconductor substrate from a normal line direction of the first surface, and has a T-shaped section in the depth direction of the substrate. The first light control member includes a first light control portion and a second light control portion extending in mutually intersecting directions in an integrated structure.
