Abstract
A planar photodiode array including a useful layer made of CdHgTe. The useful layer includes at least two superimposed doped layers, each interface between two doped layers forming a single PN junction; the useful layer has at least one separation region, extending from the upper face of the useful layer, and separating at least two useful volumes while going through the PN junction; and beyond a predetermined depth in the useful layer, the average cadmium concentration in the useful volumes is less than the average cadmium concentration in the separation region.
