Abstract

Disclosed is a radiation sensitive detector element or array and process for fabricating same wherein conductive patterns are formed on both sides of a selected radiation sensitive material. These patterns have aligned openings or discontinuities therein which define the radiation sensitive elements of the array. One of the metallization patterns is bonded via a suitable epoxy material to an insulating substrate material, and the other metallization pattern merges into electrical contact with the one metallization pattern at an electrical contact pad remote from the radiation sensitive material. Therefore, wires may be bonded to the contact pad without exerting pressure on the radiation sensitivematerial, and a good strong series electrical connection is made to the exposed radiation sensitive material by the one or lower metallization pattern.
