Abstract
An optoelectronic device for detecting radiation, comprising a semiconductor body including: a cathode region delimited by a front surface, having a first conductivity type and including a bottom layer; an anode region having a second conductivity type, which extends in the cathode region starting from the front surface and forms a surface junction with the cathode region; and a buried region having the second conductivity type, which extends within the cathode region and forms a buried junction with the bottom layer. The cathode region further includes a buffer layer, which is arranged underneath the anode region and overlies, in direct contact, the bottom layer. The buffer layer has a doping level higher than the doping level of the bottom layer.
