Abstract
A solid-state image sensor includes a semiconductor substrate having a photoelectric conversion element converting incident light into a charge and a charge retaining section temporarily retaining the charge photoelectrically converted by the photoelectric conversion element and a light shielding section having an embedded section extending in at least a region between the photoelectric conversion element and the charge retaining section of the semiconductor substrate.
Claims8
A solid-state image sensor comprising:
- a semiconductor substrate having a photoelectric conversion element converting incident light into a charge and a charge retaining section temporarily retaining the charge photoelectrically converted by the photoelectric conversion element;
- and
- a light shielding section comprising:
- an embedded section extending vertically in at least a region between the photoelectric conversion element and the charge retaining section of the semiconductor substrate, and
- a lid section extending horizontally in such a way as to cover at least the charge retaining section of the semiconductor substrate, wherein the embedded section and the lid section are directly connected to each other.
