Solid-state imaging device and imaging apparatus

A solid-state imaging device comprising:

• a semiconductor layer including;
• first and second photoelectric conversion units that are stacked in the semiconductor layer;
• and
• a longitudinal transistor having a gate electrode that is embedded in the semiconductor layer from a first surface of the semiconductor layer;
• an organic photoelectric conversion unit that is arranged over a second surface of the semiconductor layer, wherein the second surface is a light incident surface of the semiconductor layer;
• and
• a wiring layer disposed between the organic photoelectric conversion unit and the second surface of the semiconductor layer,
• wherein a charge generated in the organic photoelectric conversion unit is transferred to a first floating diffusion formed at a side of the first surface of the semiconductor layer via the wiring layer.
