Patent ID: 7807010

Claim:
A method for producing an array for detecting electromagnetic radiation said array consisting of a plurality of elementary detection modules mounted on an interconnect substrate and said modules themselves comprising at least one circuit for detecting said radiation, connected to a read circuit by hybridization, said read circuits themselves being attached to interconnect substrate, wherein the method comprises: making, on the rear face of read circuit of each of the elementary modules: grooves or slots designed to allow migration of an adhesive capable of ensuring attachment of said modules on interconnect substrate, and areas without such grooves or slots in order to allow direct contact between said modules and said interconnect substrate; mounting, firstly on the front face of interconnect substrate, and secondly on the front face of the detection circuit, registration features capable of ensuring accurate positioning, on the X and Y axes, of each of the elementary modules on said interconnect substrate; bringing about pressing of each of the elementary modules onto interconnect substrate after positioning of said modules, areas which have no grooves or slots on the rear face of read circuit then being in direct contact with interconnect substrate; ensuring migration of the adhesive through grooves or slots provided for this purpose; raising the temperature of the chamber used to produce said array in order to cause curing of the adhesive.
