Method of manufacturing infra-red detector

A method of manufacturing an infra-red detector device, comprising the steps of providing at least one detector element of infra-red sensitive material having at one major side at least one active surface area defined between a pair of electrically conductive contact layers spaced apart on the surface and which extend over a pair of oppositely curve edges of the element at the said one major side, adhering the opposite major side of the element to an insulating substrate provided on one surface with an electrically conductive pattern of lead-out conductors, the said oppositely located curved edges of the element being located in the proximity of oppositely located end portions of lead-out conductors of the pattern, and applying electrically conductive material to form interconnections between the contact layers on the element and the adjacently situated end portions of the lead-out conductors, said interconnections extending as conductive layers on the upper surface of the lead-out conductors and at least on those portions of the contact layers of the element situated over the said curved edges at the one major side.
