Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An electronic apparatus, comprising:
a solid-state imaging element including:
a semiconductor substrate including a photoelectric conversion section for each pixel;
a pixel transistor provided on one surface of the semiconductor substrate; and
an element separation section provided in the semiconductor substrate and including a first element separation section and a second element separation section that have mutually different configurations,
wherein the first element separation section extends beyond the one surface of the semiconductor substrate and overlaps with the photoelectric conversion section in a cross-sectional view and the second element separation section extends beyond the one surface of the semiconductor substrate in the cross-sectional view,
wherein the element separation section defines an active region of the pixel transistor,
wherein the second element separation section has, on a side surface, a first semiconductor region and a second semiconductor region that have mutually different impurity concentrations in a depth direction of the second element separation section, and
wherein a conductive type of each of the first and second semiconductor regions is different than a conductive type of the photoelectric conversion section.
