Paper Abstract

We describe the construction, operation, and performance of a staring IRCCD focal plane that utilizes platinum silicide Schottky barrier diodes on p-type silicon as the infrared detector. The 25X50 element array is fabricated with standard integrated circuit grade silicon and uses an interline transfer scheme consisting of 25 vertical column buried channel CCD shift registers and one horizontal shift register. The device is operated at a temperature of about 80°K and is sensitive in the 1.2 to 4.5 pm spectral region. A signaL processor is also described which provides a non-interlace television compatible video signal from the IRCCD and interfaces with the normal drive electronics. The processor provides phase locked clocks and digitally derived control pulses for accurately synchronized signals to insure excellent video stability. Central to the design of this processor is a slow in/fast out CTD time compressor which allows the video signal to be displayed as a normal full field picture on a standard television monitor. We discuss the operation and characterization of the Schottky IRCCD imager including measurements of bias dependence of the transfer characteristic and device quantum yield. In addition, data are presented on thermal response, integration element size, transfer efficiency, MRT and noise characteristics. Future improvementsin Schottky IRCCD technology are discussed.
