Abstract
An array of mesa photodiodes, including a useful layer of CdHgTe wherein pads are formed. The array includes a first doped zone having a first N or P doping; and second doped zones having a second P or N doping of a different type from that of the first doping, and each extending on an upper region of a pad. The first doped zone includes at least one first region having a first doping density, located at least under each of the pads; and at least one second region, located between two neighboring pads, and having a second doping density higher than the first doping density, each second region being separated from the closest second doped zone by at least one portion of the first region.
