摘要:
A solid-state image pickup apparatus includes a photoelectric conversion unit, a charge storage unit, and a floating diffusion unit, all disposed on a semiconductor substrate. The solid-state image pickup apparatus further includes a first gate electrode disposed on the semiconductor substrate and extending between the photoelectric conversion unit and charge storage unit, and a second gate electrode disposed on the semiconductor substrate and extending between the charge storage unit and the floating diffusion unit. The solid-state image pickup apparatus further includes a light shielding member including a first part and a second part, wherein the first part is disposed over the charge storage unit and at least over the first gate electrode or the second gate electrode, and the second part is disposed between the first gate electrode and the second gate electrode such that the second part extends from the first part toward a surface of the semiconductor substrate.
