Paper Abstract

This paper describes a 256 by 256 HgCdTe hybrid focal plane with a 0.9 to 2.6 μm spectral range. The silicon FET switch multiplexer (mux) is based on previous hybrid work with a 128 by 128 Reticon mux. The high-density device described has a 40 μm pixel pitch vs. 60 gm for the 128 by 128 devices. A read noise of about 1,000 e-has been obtained on developmental hybrid structures, along with full well capacities of about 1 x 106 e-. Preliminary device characterization for the 256 by 256 device, along with the first low-background astronomy test results for the 128 by 128 devices, will be presented.
