Patent attributes
A manufacturing method is provided for a photoelectric conversion device in which no plane channeling is produced. The photoelectric conversion device includes a silicon substrate and a photoelectric conversion element on one principal plane of the silicon substrate that forms an off-angle θ with at least two planes perpendicular to a reference (1 0 0) plane within a range of 3.5°≦θ≦4.5°, and an ion injecting direction for forming a semiconductor region constituting the photoelectric conversion element forms an angle θ to a direction perpendicular to the principal plane within a range of 0°<φ≦45°, and further a direction of a projection of the ion injecting direction to the principal plane forms each angle α with the two plane direction within a range of 0°<α<90°.
