Due to aggressive scientific specifications, Semiconductor Technology Associates and the University of Arizona's Imaging Technology Laboratory have collaborated to develop a fully depleted back illuminated CCD for scientific imaging. These devices are designed to target increased quantum efficiency into the near-infrared, without reduction in the modulation transfer function, charge transfer efficiency, or rms noise. The STA1700 series imagers are back illuminated 100 micron thick devices with a 10 micron pixel pitch targeted to meet the requirements of the Large Synoptic Survey Telescope (LSST). Recent characterization results will be presented including the point spread function of a 2 micron spot. Also discussed will be the thinning and packaging developments for the STA1700. These efforts include the addition of a backside bias contact, invar package design with high density connectors, as well as etching and backside coating optimization for high resistivity silicon.
