Sensors Unlimited will design, develop, and deliver a 1920x1080 element InGaAs focal plane array based camera for use in BOTH the Visible and Shortwave Infrared (SWIR) wavelength bands. Using Sensors Unlimited's proven InP substrate removal process, the short wavelength response of an InGaAs focal plane array is extended, such that the wavelength response spans from the visible (400 nm and 20% quantum efficiency) to the SWIR (1700 nm and 80% quantum efficiency). In addition, a readout integrated circuit architecture with in-pixel current amplification is utilized to achieve "noiseless" gains similar to those obtained by charge multiplying CCD image sensors. During phase I, our current 640x512 buffered input gate modulated readout integrated circuit architecture will be scaled to the 1920x1080 format at the schematic and modeling design level, with circuit layout taking place during the Phase I option period. In addition, we will demonstrate 1920x1080 pixel bump bonding technology with substrate removal on a 12.5 micron pixel pitch during Phase I. During Phase II, the readout integrated circuit and substrate removed InGaAs photodiode arrays will be fabricated and mated to miniature camera electronics, similar to our existing 320x256 MicroCamera platform.
