Abstract:
1. A charge-coupled device (CCD) solid-state imager, comprising: light receivers, which are arranged two-dimensionally on a semiconductor substrate; vertical transferers, each of which is arranged along a corresponding column of said light receivers in a vertical direction; a horizontal transferer, which is arranged adjacent to a final row of said light receivers; a floating diffusion capacity region, which is formed at an end of said horizontal transferer, and is operable to hold signal charges derived from incident light; an amplifier which is operable to convert the signal charges held in said floating diffusion capacity region into a voltage; a first wire which connects said floating diffusion capacity region to an input of said amplifier; and a second wire which is made of a same material as said first wire, formed in a same layer as said first wire, arranged around said first wire at least along long sides of said first wire, and electrically insulated from said first wire and a power wire.
