HYBRID PHOTOSENSITIVE CIRCUIT (HPC) Russian patent published in 2014 - IPC H01L31/00 B82B1/00 H01J47/00 

FIELD: physics.

SUBSTANCE: hybrid photosensitive circuit includes a diamond matrix photodetector, indium columns and a silicon multiplexer with sensitive sites arranged thereon in a staggered manner in form of a rectangular matrix and the number of which is equal to the number of indium columns. The matrix photodetector includes a diamond plate and an upper flat electrode lying thereon, as well as lower electrodes of sensitive elements of the matrix photodetector, the number of which is equal to the number of indium columns lying under the diamond plate. On the lower side of the diamond plate there are boron-doped sites arranged in a staggered manner; upper contact surfaces of odd or even lower electrodes are galvanically connected to the lower surface of the diamond plate, and the upper contact surfaces of the odd or even lower electrodes are galvanically connected the boron-doped sites. Lower contact surfaces of lower electrodes are galvanically connected through indium columns to sensitive elements of the silicon multiplexer.

EFFECT: expanding the detected radiation range 75-fold owing to simultaneous recording of the image in the ultraviolet and infrared spectrum.
