Abstract:
The present disclosure relates to a solid-state imaging device, a driving method for the same, and an electronic appliance, and an object is to provide a solid-state imaging device that can achieve the pixel miniaturization and the global shutter function with higher sensitivity and saturated charge amount. Another object is to provide an electronic appliance including the solid-state imaging device. In a solid-state imaging device  1  having the global shutter function, a first charge accumulation unit  18  and a second charge accumulation unit  25  are stacked in the depth direction of a substrate  12 , and the transfer of the signal charges from the first charge accumulation unit  12  to the second charge accumulation unit  25  is conducted by a vertical first transfer transistor Tr 1 . Thus, the pixel miniaturization can be achieved.

Claim (Index 20):
An electronic appliance comprising:\n an optical lens; a solid-state imaging device to which light condensed by the optical lens is incident and which includes a substrate, a photoelectric conversion unit that generates signal charges corresponding to light quantity, a floating diffusion unit that is provided for the substrate and that converts the signal charges into voltage, a first charge accumulation unit that is provided for the substrate and that accumulates the signal charges generated in the photoelectric conversion unit, a second charge accumulation unit that is provided on the first charge accumulation unit in a substrate thickness direction and that is formed electrically isolated from the first charge accumulation unit, a first transfer transistor that includes a first transfer gate electrode formed embedded in the substrate to a depth of such a degree that the first transfer gate electrode reaches the first charge accumulation unit from a substrate surface provided with the second charge accumulation unit, and a second transfer transistor that transfers the signal charges accumulated in the second charge accumulation unit to the floating diffusion unit; and a signal processing circuit that processes an output signal output from the solid-state imaging device.
