Abstract

The current state-of-the-art in large format near-IR detector array fabrication is discussed. Near-IR detector arrays of 1024 by 1024 pixels format, both in HgCdTe and InSb, are now in use in many astronomical instruments and are performing very well. The next step in detector array size has just been taken and Rockwell has produced the first science-grade 2048 by 2048 HgCdTe array. Further advances in performance are required for medium and high resolution spectroscopy and for future space missions, in particular the next generation space telescope. Technologies are being developed that will allow us to overcome most of the performance limitations of today's near-IR detector arrays.
