Abstract:
A solid-state image sensing device comprising:photoelectric conversion elements two-dimensionally arrayed in a matrix on a semiconductor substrate; transfer gate portions respectively arranged adjacent to each of said photoelectric conversion elements to read signal charges stored in said photoelectric conversion element; a vertical CCD arranged adjacent to said transfer gate portions to transfer the signal charges read from said photoelectric conversion elements in a vertical direction; a horizontal CCD for transferring the signal charges transferred from said vertical CCD in a horizontal direction; and a charge detection portion for detecting the signal charges transferred from said horizontal CCD and outputting the signal charges, wherein the vertical CCD comprises groups of four vertical transfer electrodes corresponding to respective pixels adjacent to each group of four vertical electrodes, the four vertical transfer electrodes comprising a first vertical electrode that serves as a transfer electrode for controlling the transfer gate portion of a corresponding pixel, a second vertical transfer electrode adjacent the first vertical transfer electrode, a third vertical transfer electrode adjacent the second vertical transfer electrode, and a fourth vertical transfer electrode adjacent the third vertical transfer electrode, and wherein, among said vertical transfer electrodes of the group of four vertical electrodes, said first vertical transfer electrode has the largest length, and said third vertical transfer electrode has the second largest length.
