Abstract: An imager, an image sensor included in the imager and a method of fabricating the image sensor are provided. The image sensor having a substrate with front and back sides to produce image data, includes a transparent conductive coating arranged on the back side of the substrate, a first well region of a first conductive type having first and second opposite sides, the first side being arranged adjacent with the front side of the image sensor; and a second well region of a second conductive type, different from the first conductive type and having a deep well region provided adjacent with the second side of the first well region, the transparent conductive coating configured to develop or to receive a first potential and the first well region configured to receive a second potential to substantially deplete a region between the transparent conductive coating and the first well region.

Abstract: A monolithically-integrated semiconductor/ superconductor infrared detector and readout circuit providing sensitive, low-noise detection of infrared radiation for high-performance focal plane array applications. The infrared detector and readout circuit includes a semiconductor infrared detector and a semiconductor/superconductor transimpedance readout amplifier fabricated directly on the infrared detector using thin-film, integrated-circuit processing techniques. A superconducting analog-to-digital (A/D) converter digitizes the detector signals in the cryogenically cooled environment of the detector before coupling the signals to the much warmer and electromagnetically noisier environment of the back-end signal processing electronics, thus reducing noise contamination.
