TL;DR: In this article, a new transfer region structure is proposed to eliminate the fixed pattern noise caused by incomplete signal charge transfer between two CCD registers, due to the potential dip and barrier formed in the transfer region.
Abstract: A dual-channel horizontal-CCD (H-CCD) register scheme is essential to realizing high-density image sensors. However, fixed pattern noise will appear, unless precise care is taken in designing a transfer region connecting two H-CCD registers. This paper indicates that the fixed pattern noise is caused by an incomplete signal charge transfer between two H-CCD registers, due to the potential dip and barrier formed in the transfer region. A new transfer-region structure is proposed. It has been confirmed that the fixed pattern noise can be eliminated by this new structure. >
