Patent ID: 7768085

Claim:
A photodetector array comprising: a semiconductor substrate having first and second main surfaces opposite to each other and having a first layer of a first doping concentration proximate the first main surface and a second layer of a second doping concentration proximate the second main surface, the first and second layers being of a first conductivity; at least one conductive via formed in the first main surface, the at least one via extending to the second main surface of the semiconductor substrate, the at least one conductive via being isolated from the semiconductor substrate by a first dielectric material; an anode/cathode region proximate the first main surface and the at least one conductive via, the anode/cathode region being of a second conductivity opposite to the first conductivity; and a doped isolation region formed in the first main surface and extending through the first layer of the semiconductor substrate to at least the second layer of the semiconductor substrate, the doped isolation region having a third doping concentration different than the first doping concentration.
