Abstract

Nine imagers that exploit distinctive CID properties and incorporate on-chip amplifier configurations (including preamplifier/pixel) were developed for use in automation, nuclear and scientific applications. TV compatible (11 mm) formats of 768_H X 575_V (European) and 755_H X 484_V (domestic-RS170) were fabricated for radiation- hardened product cameras. Operating CIDs provided excellent signal-to-noise at radiation levels of 10⁶ rads/hr, and accumulated dose beyond 10⁶ rads in silicon (⁶⁰Co source). Large format imagers featuring random pixel and subarray addressability, were created for spectroscopy and other scientific applications. They possess a 27 X 27 micrometers ² pixel in 1024_H X 1024_V, 1024_H X 256_V, and 512_H X 512_V formats. Pixels and subarrays (even overlapping subarrays) can be read out destructively or non-destructively. The above features can be combined with 2D on- CID pixel binning because CID binning preserves the spatial fidelity of the pixel charge. Two 1024 linear-type imagers were fabricated with a preamplifier-per-pixel structure and a 27 X 150 micrometers ² large capacity photo-site. One device features on-chip large signal differencing capability between successive exposures. Two 512_H X 512_V (20 X 20 micrometers ² pixel) format imagers were created for UV photon-counting applications. The imagers provide high local count rates through video-rate random subarray addressability and subarray charge injection.
