Abstract

A method of positioning elements or additional technological levels on the incident surface of an infrared detector of hybridized type, said detector being formed of a detection circuit comprising an array network of photosensitive sites for the wavelength ranges of interest, hybridized on a read circuit, said detection circuit resulting from the epitaxial growth of a detection material on a substrate, comprising forming within the detection circuit indexing patterns by marking of the growth substrate.
