Abstract

PURPOSE: To prevent a disapperance of a carrier produced by a light signal due to a sweep-out by making up of a desirable light receiving portion with light blocking insulation layer making a partial overlapping over an electrode end portion on an infrared ray element in the light receiving face side.
CONSTITUTION: An infrared ray detecting wafer including Hg1-xCdxTe and others is bonded on a support plate 31, for example, Si with a high specific resistance by utilizing a bonder, thereafter to form a chip 32 having a predetermined shape by a polishing and etching. Successively, an electrode 33 is vapor-bonded on the chip 32 by a metal of In and other. In addition, an electric insulation material for blocking the infrared ray, for example, SiO2 and others is bonded on the chip 32 having the electrode 33 formed thereon so that a part of the above material is overlapped over the end of the electrode 33, and an opening with a predetermined area is provided by a photo etching to form the light receiving face A.
