TECHNICAL ABSTRACT (LIMIT 200 WORDS)
We propose to investigate the feasibility of developing a two-dimensional far infrared photoconductor array with the following key design features:

1- A top-illuminated, 2D germanium array (32x32 single or 64x64 mosaic) with the possibility of extension to very large formats. The quantum efficiency is enhanced by metalizing the bottom surface for a second pass.

2- A 2-side buttable 32x32 (64x64 mosaic) CTIA readout multiplexer using advanced cryo-CMOS process. The unit-cell design is optimized for far IR detectors, eliminates detector debiasing, and improves pixel uniformity. The readout is operational down to at least 2.0K.

3- A novel, direct hybrid design using indium-bump technology. This integrated design offers superior noise performance and effectively addresses the readout glow, detector heating, and thermal mismatch between the detector and the readout. This is the key discriminator of this project.

The projected sensitivity of this array as well as >1 kpixel (64x64 mosaic) format meets the stated requirements of future NASA instruments. This effort fits well within the scope of the SBIR Subtopic S4.01 and will be a benefit to many large and small NASA projects such as SOFIA and SAFIR.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
ace instruments developed under Origins Program such as SAFIR, science instruments for SOFIA, upcoming projects under Astrobiology Program, balloon-borne instruments for atmospheric research, and laboratory science instruments.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
Aerospace industry: In addition to the aerospace companies that are under contract to NASA and directly participate in the space program, there are those that independently manufacture infrared detector arrays in large formats. Some aerospace companies that would be interested in our product are Raytheon Vision Systems, Boeing, Rockwell, and Ball Aerospace. Science groups at universities and national labs: Astronomical science instruments for observations at ground-based observatories and instruments for basic research.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
