Title:
MANUFACTURE OF SEMICONDUCTOR RADIATION DETECTOR
Document Type and Number:
Japanese Patent JPH0461173
Kind Code:
A
Abstract:
PURPOSE:To improve the workability of assembly, and to prevent the ununiformity of the characteristics of each radiation detecting element by fixing one electrode of the radiation detecting element to a conductive base body by a conductive fixing material and connecting the other electrode to a member fixed to the conductive base body. CONSTITUTION:A cadmium telluride semiconductor crystal is cut out, and electrodes 10b, 10c are formed on both surfaces of the cadmium telluride semiconductor crystal 10a, thus forming a radiation detecting element 10. The electrodes 10c are bonded on the copper-foil conductors 16a of a printed board 16 by silver-epoxy conductive adhesives, and a plurality of the radiation detecting elements 10 are fastened respectively. The copper-foil conductors 16a of the printed board 16 and the noses of lead terminals 14 are connected by bonding wires 18. The electrodes 10b on the radiation incident plane sides of the radiation detecting elements 10 and the stepped section 12a of a case 12 are connected by bonding wires 20, and the electrodes 10b are connected.
