Abstract :
The AFRL has pursued high temperature IR FPAs for three years. A 10 K increase has been obtained to date by thinning the HgCdTe base-layer. A contract has recently been let to DRS Infrared Technologies to further increase operating temperature by 15 K utilizing their gold doped High Density Vertically Integrated Photodiode (HDVIP TM) technology. The increased operating temperatures of these devices will reduce power, weight, and cost, as well as extend the lifetime of space surveillance satellites, satisfying a critical 21st century device technology need
