Title: PHOTODIODE MATRIX WITH ISOLATED CATHODES
Abstract:
The invention relates to a photodiode matrix and to the method for manufacturing same, said matrix comprising a substrate (4) of indium phosphide, an active layer (5) of indium gallium arsenide above the substrate (4), a buried region (8) between the substrate (4) and the active layer (5), and an upper layer (6) made of indium phosphide above the active layer (5), a photodiode anode made up of a doped region (12), said doped region (12) extending from the upper layer (6) into the active layer (5) without reaching the buried region (8), said doped region (12) defining a plurality of cathode areas (13) of the upper layer (6) isolated from one another by the doped region (12).
