Abstract:
A photodetection device including a diode array and a method for production thereof. In the device, each diode of the array includes an absorption region having a first bandgap energy and a collection region having a first doping type, and adjacent diodes in a network are separated by a trench including sides and a bottom. The bottom and sides of the trench form a stabilization layer having a second doping type, opposite the first doping type, and a bandgap energy greater than the first bandgap energy of the absorption regions.

Claim (Index 22):
A method for manufacturing a photodetection device including an array of diodes, wherein each diode of the array includes an absorption region in an absorption layer supported by a substrate, the absorption region having a first bandgap energy, and a collection region which has a first doping type, the method comprising:\n forming trenches separating adjacent diodes in the array, each trench including flanks and a bottom which result from etching the absorption layer and which delimit an internal face of the trench on the substrate side and an external face of the trench; forming a passivation layer which covers each diode except for the trenches and contact regions of an electrically conductive stud with a collection region of a diode; forming a stabilization layer along the internal face of a trench which comprises transforming the bottom and the flanks of the trench by incorporating and diffusing an impurity, the stabilization layer having a second doping type opposite to the first doping type and a bandgap energy higher than the first bandgap energy of the absorption regions.
