Abstract
A photoelectric conversion apparatus includes a plurality of photoelectric conversion circuits configured to be arranged in a semiconductor layer having a first plane and a second plane. The plurality of photoelectric conversion circuits is individually isolated by an isolation structure. The semiconductor layer includes a plurality of trench portions arranged on the first plane of each of the photoelectric conversion circuits. The plurality of trench portions is configured of a first trench portion extending in a first direction as an in-plane direction of the first plane and a second trench portion extending in a second direction as an in-plane direction of the first plane intersecting with the first direction. A filler member and an airgap are arranged in an interior of a trench portion at a position where the first trench portion and the second trench portion intersect with each other.
