Abstract
A solid-state image sensor is provided that includes a semiconductor substrate, a charge accumulator disposed in the semiconductor substrate and configured to accumulate charge, a photoelectric converter provided above the semiconductor substrate and configured to convert light to charge, and a through electrode passing through the semiconductor substrate and electrically connecting the charge accumulator with the photoelectric converter. At an end portion on the photoelectric converter side of the through electrode, a cross-sectional area of a conductor positioned at the center of the through electrode in a cut section orthogonal to a through direction of the through electrode gradually increases toward the photoelectric converter along the through direction.
