Image sensor and method of driving the same

Abstract

An image sensor having an array including a plurality of linearly arranged blocks each consisting of an n number of photodetecting elements, switching elements respectively connected in series to the photodetecting elements, control wires, provided respectively in connection with the blocks, for turning on the switching elements for each block, and signal transfer wires connected to a drive IC for signal detection, whereby charges generated by the photodetecting elements are transferred, every block, to wiring capacitances of the signal transfer wires for signal detection. In the image sensor, the control wires are laid out crossing the signal transfer wires with an interlayer insulating film layered therebetween, and at least one dummy control wire is laid out crossing the signal transfer wires through the interlayer insulating film. A pulse is applied to the dummy control wire before gate pulses are applied to the control wires.

Dependencies are inferred from the claim text.
