SEMICONDUCTOR RADIATION DETECTOR AND RADIATION DETECTION APPARATUS

PROBLEM TO BE SOLVED: To provide a semiconductor radiation detector and a radiation detecting apparatus capable of preventing degradation of detecting characteristics properly. SOLUTION: A semiconductor radiation detecting apparatus 1 comprises a semi-conductor crystal 11a, using at least one of semiconductor crystal among CdTe, CdZnTe, GaAs and Tl, sandwitched between the electrodes of a cathode C and a cathode A. At least one of the electrode has a laminated structure composed of a plurality of metals, and the first layer is formed with Pt or Au and the second layer is formed with a metal having lower hardness than Pt or Au of the first layer. The second layer composed of In is formed with electroless plating method. And, metal layers are laminated on the second layer furthermore. COPYRIGHT: (C)2008,JPO&INPIT
