Abstract
A diode radiation sensor having charge multiplication diodes and comprising a substrate with a front and a rear surface; a first layer of a semiconductor material doped with a first type of doping and arranged on the front surface of the substrate; a second layer of a semiconductor material doped with a second type of doping of electrically opposite sign to the first type and arranged to create a high electric field region between the first and the second layer; a third layer of a semiconductor material doped with a the second type of doping; a first isolation region interposed between a lateral edge of a charge multiplication diode and the first and the second layer of the semiconductor materials and extending into the substrate from the front surface to the third layer so as to create a working area electrically separated from the first and the second layer.
