A 4096 X 2048-pixel three-side buttable scientific CCD imager was designed and fabricated for use in electronic imaging applications that require mosaics of many closely spaced large area CCDs that have good low-light-level performance. The three-side buttable CCD design, which allows 8192 X (N X 2048) pixel mosaicking, was fabricated using a custom three-level polyscientific CCD process. The CCD has 15 micron square pixels and employs a full-frame MPP mode device architecture with a single split serial shift register and two on-chip amplifiers. Excellent performance characteristics were demonstrated, including less than 5 electron noise at a 50 kHz output data rate, charge transfer efficiency greater than 0.999997, and an exceptionally low density of small signal charge traps at the characterization temperature. The on-chip CCD amplifier high-frequency operation was characterized separately and the amplifier was found to support a 5-MHz output data rate corresponding to a readout cycle of 0.84 seconds for higher frame rate applications.
