Paper Abstract

Preliminary findings are presented for a new approach that significantly improves the quantum efficiency of the current generation of high-performance, thinned, backside illuminated silicon CCDs. Experiments have shown that the application of an ultra-thin (less than 4a) layer of metal with high work function to the backside of the CCD can yield 100% internal quantum efficiency in the visible, UV, XUV and soft X-ray regions of the spectrum. Theory and solid state models describing the new technique (which we refer to as the CCD flash gate), plus a considerable amount of experimental data are discussed in this paper. Specific recommendations for use of the flash gate in present and future CODs are also reviewed.
