Disclosed is a method for producing an array for detecting electromagnetic radiation, the array including a elementary detection modules mounted on an interconnect substrate, the modules comprising at least one circuit for detecting the radiation, connected to a read circuit by hybridization, the read circuits being attached to the interconnect substrate, the method including making, on the rear face of read circuit of each of the elementary modules grooves or slots, and areas without such grooves or slots; mounting, on the front face of the interconnect substrate, and on the front face of the detection circuit, registration features that ensure accurate positioning of each of the elementary modules on the interconnect substrate; pressing each elementary module onto the interconnect substrate after positioning; ensuring migration of the adhesive through grooves or slots; raising the temperature of the chamber used to produce the array to cure of the adhesive.
