摘要： A solid state imaging device has a pixel region composed of a matrix of pixel cells each including a photodiode and a charge storage portion. First and second output signal lines are in parallel and adjacent to both the charge storage portions of a first pixel cell and a second pixel cells that are adjacent on a same column. A signal voltage of a signal charge in the charge storage portion of the first pixel cell is output to the first output signal line, whereas a signal voltage of a signal charge in the charge storage portion of the second pixel cell is output to the second output signal line. The respective outputs to the first and second output signal lines are processed in parallel. A conductive layer is disposed between the charge storage portion of the first pixel cell and the second output signal line to suppress capacitive coupling.

摘要： A dummy cell includes two series-connected OFF-state transistors, one end of the series circuit which is formed by these two transistors is connected with a constant voltage source, and the other end of the series circuit is connected with a replica bit line. This suppresses a leak current flowing from the replica bit line to the dummy cell and therefore gives optimal start-up timing to a sense amplifier circuit.

摘要： A pixel array is provided in which cells are arranged in a matrix. Each cell includes a photodiode, an FD, a transfer transistor, a reset transistor, an amplifying transistor having a gate electrode connected to the FD, a drain connected to a power supply line, and a source connected to a vertical signal line, and an FD wire. The FD wire is provided in a first wiring line, and the vertical signal line is provided in a second wiring line positioned over the first wiring layer. Since the potential of the FD wire follows the potential of the vertical signal line, it is possible to suppress a variation in capacitance occurring in the FD when a position of the vertical signal is shifted, depending on a position of the cell.

The dummy cell is connected as a load with the common replica bit line. The source of a drive transistor of the dummy cell is connected with a power source which is at the High level. This suppresses a leak current flowing from a replica bit line to the dummy cell.
