Claim of US Patent No. 10,715,768

1. An imaging device comprising:a first photoelectric conversion region disposed in a semiconductor substrate;
a first gate of a first transistor, a part of the first gate of the first transistor being disposed in the semiconductor substrate, wherein the part of the first gate of the first transistor comprises a first end at a first surface of the semiconductor substrate; and
a second gate of a second transistor, a part of the second gate of the second transistor being disposed in the semiconductor substrate, wherein the part of the second gate of the second transistor comprises a second end at the first surface of the semiconductor substrate,
wherein a first part of the first photoelectric conversion region is disposed between the part of the first gate of the first transistor and a second surface of the semiconductor substrate, the second surface of the semiconductor substrate being opposite the first surface of the semiconductor substrate, and
wherein the part of the first gate of the first transistor comprises a third end in the semiconductor substrate, the part of the second gate of the second transistor comprises a fourth end in the semiconductor substrate, and the third end of the part of the first gate of the first transistor and the fourth end of the part of the second gate of the second transistor are disposed at the same depth of the semiconductor substrate.
