Abstract
A solid-state image pickup device includes a semiconductor substrate in which photoelectric conversion units are arranged. An insulator is disposed on the semiconductor substrate. The insulator has holes associated with the respective photoelectric conversion units. Members are arranged in the respective holes. A light-shielding member is disposed on the opposite side of one of the members from the semiconductor substrate, such that only the associated photoelectric conversion unit is shielded from light. In the solid-state image pickup device, the holes are simultaneously formed and the members are simultaneously formed.
