Paper Abstract

The development of a PtSi array for use in ground-based astronomy has been the goal of a joint effort between the National Optical Astronomy Observatories (NOAO) and the Hughes Microelectronics Center. This has been accomplished by the introduction of the SWIR PtSi hybrid array for astronomy. The resulting array has an optical cavity tuned to enhance the internal quantum efficiency at 1.7 microns, low noise, and low dark current. The use of PtSi Schottky detector material yields high uniformity and exceptional stability of performance compared to other SWIR materials. Hybrid technology allows the array to achieve the 100% fill factor needed for astronomical applications and the NMOS SFD readout yields very low noise performance. In this paper we describe these characteristics in more detail and present test data to demonstrate the array performance.
