Large Format, 1280x1024 Longwave HgCdTe Focal Plane Arrays

"This Small Business Innovation Research project develops large format (1280x1024), longwave infrared (LWIR) HgCdTe focal plane array (FPA) cameras. The LWIR HgCdTe arrays will be fabricated by ion implantation. In Phase I, two types of implantations willbe conducted to fabricate 320x256 LWIR arrays. The first is using boron implantation to produce n-on-p type diodes, and the second is to use arsenic implantation to produce p-on-n type diodes. The superior technique between these two will be used tofabricate 1280x1024 LWIR HgCdTe arrays in Phase II. Readout circuits matching the arrays will also be designed and manufactures. After hybridizing the HgCdTe arrays to the readout chips, imaging pictures will be taken by the LWIR cameras. In Phase III,the technology and products will be commercialized. High performance, large format HgCdTe infrared focal plane array cameras have a large variety of military and civilian applications. Military uses include target detection, surveillance, searching andtracking, and material property analysis. Civilian uses include spectroscopy, medical imaging, firefighting, searching and rescue, crop surveys, law enforcement, and environmental monitoring."
