Abstract

The XCED (extrinsic charge-extraction device) is a unique focal-plane array structure designed for staring infrared-imaging applications. Extrinsic-silicon detectors, MOS integrating storage capacitors, and unique accumulation mode multiplexing devices are combined in a two-dimensional array within a single monolithic chip. Zinc-doped silicon has been studied and utilized to fabricate detectors sensitive in the 2 to 4 Ilm spectral band with BLIP operating temperatures above 110°K. The potentially severe problems for staring arrays of element-to-element nonuniformities and detector storage saturation have been solved. Preliminary results and thermal imagery are shown for a 16 x 16 element array.
