Patent ID: 8710448

Claim:
A radiation detector comprising: a scintillator; a photodetector array comprising: a semiconductor substrate, including: a plurality of photodetector elements in optical communication with the scintillator; and a CMOS metalization side, opposite the scintillator, wherein the metallization side includes alternating insulating and metal layers and is a part of the semiconductor substrate; and signal processing electronics carried on a side of the photodetector array opposite the scintillator; wherein the metalization side includes a first plurality of contacts electrically connected to the photodetector elements, a second plurality of contacts in electrical communication with the first plurality of contacts and the signal processing electronics, wherein the metalization side includes a first metalization layer that connects at least one discrete component and the second plurality of contacts, a second metalization layer that connects the first plurality of contacts to the second plurality of contacts, and a third metalization layer located between at least a portion of the first metalization layer and at least a portion of the second metalization layer.
