Abstract
A radiation detector unit includes a read-out integrated circuit (ROIC) including a plurality of core circuit blocks located on a continuous uninterrupted substrate adjacent to one another along a first direction, and a plurality of radiation sensors bonded to a front side surface of the ROIC, where each radiation sensor of the plurality of radiation sensors is bonded to a respective core circuit block of the plurality of core circuit blocks of the ROIC. Additional embodiments include detector modules and detector arrays formed by assembling the detector units, and methods of operating and manufacturing the same.
Claims18
A radiation detector unit, comprising:
- a read-out integrated circuit (ROIC) comprising a plurality of core circuit blocks located on a continuous uninterrupted substrate adjacent to one another along a first direction;
- and
- a plurality of radiation sensors bonded to a front side surface of the ROIC, wherein each radiation sensor of the plurality of radiation sensors is bonded to a respective core circuit block of the plurality of core circuit blocks of the ROIC,
- wherein the radiation sensors are directly bonded to the front side surface of the ROIC such that no interposer is used to route event detection signals from the radiation sensors to the core circuit blocks of the ROIC, and
- the ROIC further comprises a power bus that extends from a peripheral circuit block to each of the core circuit blocks along the first direction, and wherein each of the core circuit blocks comprises a low dropout regulator configured to provide an identical supply voltage to each of the core circuit blocks.
