Solid-state imaging apparatus and electronic apparatus

An electronic apparatus, comprising:

• an image processor;
• and
• an imaging device, comprising:
• a substrate;
• a plurality of photoelectric conversion elements in the substrate, wherein each of the plurality of photoelectric conversion elements includes an N-type region that performs photoelectric conversion;
• a light-shielding wall between a first photoelectric conversion element and a second photoelectric conversion element of the plurality of photoelectric conversion elements in the substrate in a cross-sectional view;
• a first P-type region between the first photoelectric conversion element and the light-shielding wall in the cross-sectional view;
• a second P-type region adjacent to the first P-type region and between the first photoelectric conversion element and a light incident side of the substrate in the cross-sectional view;
• and
• a vertical-type transistor extending in a depth direction of the substrate in the cross-sectional view, wherein a gate of the vertical-type transistor includes two trench-type electrodes.
