Solid-state image pickup device and method for manufacturing same, and image pickup apparatus

An image pickup apparatus comprising:

• a focusing optical unit focusing incoming light;
• a solid-state image pickup device comprising a plurality of pixels, each pixel configured to include a sensor unit capable of photoelectric conversion, the solid-state image pickup device further comprising (a) a semiconductor substrate, (b) a charge storage region of a first conduction type in said semiconductor substrate and configured to be a sensor unit and a main charge storage region, (c) a charge storage sub-region, made of an impurity region of the first conduction type, said charge storage sub-region comprising a plurality of layers in said substrate below said charge storage, and (d) a device isolation region in said semiconductor substrate configured to isolate said pixels from one another, said device isolation region made of an impurity region of a second conduction type,
• wherein,
• at least one charge storage sub-region layer extends across each pixel to the device isolation region;
• and
• a signal processor processing a signal obtained by the photoelectric conversion with said solid-state image pickup device.
