Abstract
An image sensor that comprises a first substrate and a plurality of photo detector assemblies disposed on or in the first substrate. Each of the photo detector assemblies comprises a photo detector formed on or in a second substrate and configured to generate an analog signal in response to received light, a converter formed on or in a third substrate, wherein the converter is electrically coupled to the photo detector and includes circuitry for converting the analog signal to a digital signal, a processor formed on or in a fourth substrate, wherein the processor is electrically coupled to the converter and includes circuitry for processing the digital signal.
