Patent ID: 7595829

Claim:
A solid-state image pickup device, comprising: a plurality of pixels, each of which includes a photodiode and a transfer gate electrode for transferring a charge accumulated in the photodiode and which are disposed in a pixel region of a surface of a semiconductor substrate; a plurality of floating diffusions, each of which is provided for a pixel pair including two pixels adjacent in a column direction; a plurality of MOS-type amplifier transistors, respectively having gate electrodes respectively connected to the floating diffusions; and a plurality of first wirings, each of which connects the transfer gate electrodes of two pixels adjacent in a row direction, wherein: light receiving regions of the photodiodes, the transfer gate electrodes, the floating diffusions have outer shapes consisting of lines extending in row directions and lines extending in column directions and are disposed in an axisymmetrical manner with respect to a straight line extending between a pair of the photodiodes included in the pixel pair, and the first wiring connecting the transfer gate electrodes of the two pixels adjacent in the row direction is unified with the transfer gate electrodes.
