FUNCTIONALLY INTEGRATED PHOTOSENSITIVE MATRIX CELL Russian patent published in 2014 - IPC H01L31/113 H01L27/14 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to microelectronics and more specifically to photosensitive matrices of receivers of optical and X-ray radiation and images for use in photographic cameras, video cameras, cellular telephones, medical X-ray panels, as well as in universal solid-state screens, capable of both receiving a photographic image and displaying it on the same screen. The functionally integrated photosensitive matrix cell according to the invention includes a photosensitive cell, common, power, address and bit buses, a line selection transistor whose gate is connected to the address bus, wherein the cell further includes a capacitor and a bipolar n-p-n (p-n-p) transistor whose collector is connected to the power bus, and the emitter is connected to the bit bus, the base is connected to the drain of a p(n) channel MOS transistor for line selection, the common bus is connected to the first capacitor lead, the second lead of which is connected to the collector of the bipolar transistor. The invention also discloses three other versions of the functionally integrated photosensitive matrix cell.

EFFECT: invention improves sensitivity, operating speed of the photosensitive matrix and enables dual use as an image receiver and transmitter.
