DOD / MDA
In this Phase II effort, SK Infrared LLC, is collaborating with Raytheon Vision Systems (RVS) to demonstrate a dual color 512x512 30 um pitch long wave/long wave (LW/LW) pBp focal plane array (FPA) hybridized to a RVS SB410 Read Out Integrated Circuit (ROIC). The SB410 is a 512x512 30 micron pitch dual band ROIC developed by RVS. The final deliverable at the end of the two year project would be a dual color (LWIR & #61548;1~8.5 & #61549;m and LWIR & #61548;2~10.5 & #61549;m) 512x512 FPA with dark current density ~1e-6 A/cm2 and QE=70% at operating bias (~100 mV). The design, growth and fabrication of the device till the indium bump deposition will be done at SK Infrared LLC (SKI) using the user facilities at the Center for High Technology Materials at the University of New Mexico. The devices will be hybridized and radiometrically characterized at Raytheon Vision Systems (RVS).
