Abstract
A photoelectric conversion apparatus includes a semiconductor substrate having one principle surface including recessed portions, and insulation bodies in the recessed portions. The semiconductor substrate includes photoelectric conversion elements each of which includes a first semiconductor region of a first conductivity type, a second semiconductor region of a second conductivity type, and a third semiconductor region of the second conductivity type which has at least a portion disposed nearer to the principle surface relative to the second semiconductor region. The second semiconductor region has a polarity of signal charge. The second semiconductor region is in contact with the first and third semiconductor regions. Signal charge paths are disposed between the recessed portions in a cross section perpendicular to the principle surface. At least one of the second and third semiconductor regions is positioned in directions of at least two of the signal charge paths.
