Abstract

The invention relates to a radiation detector and a method for its production, wherein a series of converter plates (110) and interconnect layers (120), which extend into a border volume (BV) lateral of the converter plates (110), are stacked. By filling voids in the border volume (BV) with an underfill material and cutting through the border volume, a contact surface (CS) is generated in which electrical leads (123) of the interconnect layers (120) lie free. To allow a good contacting, said leads (123) are preferably provided with enlargements in the contact surface, for example by bonding wires (132) to them.
