Patent ID: 7701026

Claim:
An imaging device comprising: a semiconductor substrate having a first main surface and a second main surface, the second main surface is opposite to the first main surface and is passed by a light to be detected, a plurality of photodiodes formed on the first main surface of the semiconductor substrate, a wiring layer provided on the first main surface of the semiconductor substrate, and a plurality of bumps provided on the wiring layer, wherein at least one of the plurality of bumps is disposed overlapping with one of the plurality of photodiodes in a planar view, wherein a peripheral circuitry is formed at a region of the first main surface of the semiconductor substrate where the plurality of photodiodes are not formed, and at least one of the plurality of bumps is disposed overlapping with the periphery circuit in, and wherein the peripheral circuitry includes a row decoder, a sense amplifier, and an I/O circuit.
