Abstract:
An imaging device having a first surface on which light is incident and a second surface on an opposite side of the first surface, includes a photoelectric conversion section including semiconductors having a same conductivity type, in which an impurity concentration on the second surface side is higher than an impurity concentration on the first surface side.

Claim (Index 1):
An imaging device comprising\n a semiconductor substrate having a first surface on which light is incident and a second surface on an opposite side of the first surface, the semiconductor substrate comprising:\n a photoelectric converter including a first semiconductor region arranged on a side of the first surface and a second semiconductor region arranged on a side of the second surface and having a higher impurity concentration than the first semiconductor region; and \n a transfer gate arranged on the second surface side and transferring a charge subjected to photoelectric conversion by the photoelectric converter, wherein \n the first semiconductor region has an impurity concentration gradient in which its impurity concentration increases from the first surface of the semiconductor substrate toward the second semiconductor region.
