Paper Abstract

A review is given of some aspects of a large-format image sensor which combines an a-Si:H thin-film sensor array with microelectronic chips for readout, interconnected on one substrate. Comparisons are made between the different thin-film photoconductor materials, the various noninjecting contacts for the sensor photodiodes and the circuits for readout as they have been proposed so far. A-Si:H is found to be a superior material for the sensors; however, the readout circuit must be carefully designed to obtain a satisfactory signal at the sensor output.
