Patent ID: 7884436

Claim:
A solid-state imaging device comprising: a semiconductor substrate with a first surface and a second surface opposite the first surface; a plurality of light reception regions formed in the semiconductor substrate, respectively having first surface side regions formed in a first surface side part on the first surface of the semiconductor substrate and second surface side regions formed in a second surface side part on the second surface of the semiconductor substrate; and a pixel circuit formed on the first surface side of the semiconductor substrate and shared by the plurality of light reception regions, wherein the second surface side, opposite the first surface side where the pixel circuit is formed, of the semiconductor substrate is made a light incident side of the light reception regions, and the second surface side regions of the light reception regions formed in the second surface side part are arranged at approximately even intervals and the first surface side regions of the light reception regions formed in the first surface side part are arranged at uneven intervals, respectively, and the second surface side regions and the first surface side regions of the light reception regions are joined respectively in the semiconductor substrate so that the light reception regions extend from the second surface side to the first surface side of the semiconductor substrate.
