Abstract:
An imaging device includes a semiconductor substrate having a surface, the semiconductor substrate including: a first layer of a first conductivity type; a second layer of a second conductivity type, the second layer being closer to the surface; and a pixel including: a photoelectric converter configured to convert light into charge; a first diffusion region of the first conductivity type, the first diffusion region facing the first layer via the second layer, configured to store at least a part of the charge; and a second diffusion region being a diffusion region closest to the first diffusion region among diffusion regions of the first conductivity type, the diffusion regions facing the first layer via the second layer. A distance between the second diffusion region and the first layer is equal to or less than 1.5 times a distance between the second diffusion region and the first diffusion region.

Claim (Index 10):
An imaging device comprising:\n a semiconductor substrate having a first surface, the semiconductor substrate including:\n a first layer containing an impurity of a first conductivity type; \n a second layer containing an impurity of a second conductivity type different from the first conductivity type, the second layer being closer to the first surface; and \n a pixel including:\n a photoelectric converter configured to convert light into charge; \n a first diffusion region containing an impurity of the first conductivity type, the first diffusion region facing the first layer via the second layer, configured to store at least a part of the charge; and \n a second diffusion region being a diffusion region closest to the first diffusion region among diffusion regions containing an impurity of the first conductivity type, the diffusion regions facing the first layer via the second layer, wherein \n a potential curve in a depth direction from the first surface of the semiconductor substrate along a line passing through a center of the first diffusion region has a first range where a potential decreases monotonously as a depth increases, a second range where the potential increases monotonously as a depth increases, and a third range between the first range and the second range where an absolute value of a slope of the potential curve is smaller than an absolute value of a slope of the potential curve in each of the first range and the second range, and a width of the third range is smaller than a sum of a width of the first range and a width of the second range.
