Paper Abstract

High performance PtSi Schottky-barrier focal plane arrays (SB FPAs) have been developed for thermal imaging by using a process technology fully compatible with silicon VLSI and an original readout architecture called Charge Sweep Device (CSD). Eliminating limitations of the conventional interline transfer CCD readout architecture, the CSD readout architecture makes it possible to design small pixels with high fill factors and large saturation levels. Thanks to a high fill factor of 71 percent and a large saturation level of 2.9 X 106 electrons, a 512 X 512 element SB CSD FPA with a 26 X 20 micrometers 2 pixel size has achieved a very low noise equivalent temperature difference of 0.033 K at 300 K with f/1.2 optics and a 30 Hz frame rate. A high- resolution SB CSD FPA with 1040 X 1040 pixels has also been developed. This high-resolution FPA produces HDTV- quality IR images at the standard TV frame rate. IR cameras with these FPAs have been used and proved to be useful for a wide variety of applications.
