A MONOLITHIC SEMICONDUCTOR DETECTOR

摘要

A semiconductor radiation detector comprising a semiconductor substrate (30) on a front face of which are provided a first semiconductor well (31) and a second semiconductor well (36). The first well (31) forms a diode with the semiconductor substrate (30) and acts as a collector for collecting signals due to incident radiation. The second well (36) contains readout circuitry (37) that is connected to the collector (31), wherein a biasing contact (34) is provided for biasing the diode and the readout circuitry (37) is ac coupled to the collector (31).
