Zigzag interline transfer type CCD image sensor

A charge coupled device image sensor comprising:

• a plurality of uniformly spaced photodetecting means arranged in series in the vertical and horizontal directions, for producing signal charges corresponding to incident light incoming along a predetermined path,
• horizontal signal transferring means formed integrally in a zigzag form between adjacent sets of said plurality of uniformly spaced photodetecting means in series in the horizontal direction for transferring the signal charges being applied from said plurality of uniformly spaced photodetecting means in a single direction in response to first and second external clock signals,
• signal flowing direction changing means formed under the last set of said plurality of uniformly spaced photodetecting means in series in the horizontal direction and at output of said horizontal signal transferring means for selectively reversing a flow of the signal charges outputted from said horizontal signal transferring means in the opposite direction in response to a third external clock signal,
• signal processing means for storing temporarily the signal charges from said horizontal signal transferring means or the signal charges from said signal flowing direction changing means and then resetting the signal charges, and
• sense amplifying means for sensing states of the signal charges being temporarily stored in said signal processing means and amplifying the sensed states of the signal charges by a predetermined amplification degree;
• wherein said plurality of uniformly spaced photodetecting means, said horizontal signal transferring means and said signal flowing direction changing means are of the same conductive type as that of a substrate.
