Abstract
A photoelectric conversion apparatus includes an element isolating portion that is disposed on a side of a front surface of a semiconductor layer and constituted by an insulator, and a pixel isolating portion. The pixel isolating portion includes a part that overlaps an isolating region in a normal direction. The semiconductor layer is continuous across semiconductor regions in an intermediate plane. The part is located between a semiconductor region and another semiconductor region.
Claims1
A photoelectric conversion apparatus comprising:
- a semiconductor layer having a first surface and a second surface being opposite to the first surface,
- wherein the semiconductor layer includes a first region where at least four photoelectric conversion elements are provided, a first isolating portion constituted by a first groove, the first groove provided in the semiconductor layer and passing through a virtual plane located closer to the second surface than the first surface and provided along the second surface, and a second isolating portion constituted by a second groove provided in the semiconductor layer and passing through the virtual plane, and
- wherein the first region is located at a position between the first isolating portion and the second isolating portion in planar view.
