Patent ID: 8854517

Claim:
A solid-state imaging device, comprising: a first substrate including a plurality of pixels arranged in rows and columns, each pixel including (a) a light sensing unit generating a signal charge responsive to an amount of received light and (b) a plurality of MOS transistors reading the signal charge generated by the light sensing unit and outputting the read signal charge as a pixel signal; a second substrate including a plurality of pixel drive circuits supplying desired drive pulses to the pixels, a timing circuit, and a control circuit, wherein the first substrate is stacked on the second substrate in a manner such that each pixel drive circuit is arranged beneath a plurality of the MOS transistors formed in the first substrate and such that each pixel drive circuit is not beneath the light sensing unit, and wherein the timing circuit and the control circuit are not beneath any one of the pixels formed in the first substrate; and a connection unit, wherein the connection unit electrically connects the pixels of the first substrate to the pixel drive circuits of the second substrate arranged beneath the MOS transistors.
