Abstract

The capacitance of a radiation-sensitive diode can be considerably reduced by giving it the form of a pn junction (4) between a first semiconductor region (4) and a layer-shaped semiconductor zone, which in operation is fully depleted. The speed of such a diode is favorably influenced by the choice or the shape of the geometry of the layer-shaped zone. When the latter is formed with parts decreasing in width of thickness, an electric field is produced in these parts which accelerates the transport of minority charge carriers to a central contact.
