Classification: CPC H | IPC H

Claim 12:
13. A photodetector circuit device, the device comprising:
a photodetector array circuit having a first terminal, a second terminal, and a plurality of photodetectors, each of the photodetectors comprising
an n-type compound semiconductor (CS) material,
an CS absorption material overlying the n-type material,
a p-type CS material overlying the absorption material,
a first electrode coupled to the n-type CS material and the first terminal, and
a second electrode coupled to the p-type CS material and the second terminal;
wherein the photodetector circuit includes an illumination region configured underlying the n-type CS materials of the plurality of photodetectors; and
a readout integrated circuit (ROIC) coupled to the photodetector array circuit, the ROIC having a first input terminal, a second input terminal, and a pixel output;
wherein the first input terminal is coupled to the first terminal and the second input terminal is coupled to the second terminal at an interface region between the photodetector array circuit and the ROIC; and
wherein the ROIC is coupled to the photodetector array circuit in a flip-chip bonding configuration.
