Abstract
A digital photoimaging device is presented. The digital photoimaging device includes a photosensor array having supporting circuitry formed on a second substrate produced, for example, with CMOS process technology and photosensors formed on a first substrate. The first substrate is processed separately from the second substrate so that the photosensors formed on the first substrate can be optimized while also optimizing the circuitry formed on the second substrate. The first substrate is then placed into electrical contact with the second substrate so that signals from the photosensors on the first substrate arc received by the supporting circuitry on the second substrate. In one embodiment, the supporting circuitry includes an array of support circuits each including an analog-to-digital converter.
