Abstract
A method of positioning elements or additional technological levels (1) on the incident surface of an infrared detector of hybridized type, said detector being formed of a detection circuit (1, 10) comprising an array network of photosensitive sites (2) for the wavelength ranges of interest, hybridized on a read circuit (4), said detection circuit resulting from the epitaxial growth of a detection material on a substrate, comprising forming within the detection circuit (1, 10) indexing patterns (7, 14) by marking of the growth substrate.
