Abstract
A method for producing a matrix of electromagnetic radiation detectors made up of a plurality of elementary detection modules mounted on an interconnection substrate. The method includes depositing on the interconnection substrate a predefined number of quantities of solder or hybridization material, intended to constitute hybridization bumps for the elementary modules, in at least a first array for the nominal hybridization, and at least one second array, with the deposits of solder or hybridization material of the second array being lower in volume than those of the first array, depositing a liquid flux on the interconnection substrate, mounting the elementary modules to be hybridized on the interconnection substrate, and raising the temperature of a chamber in which the various elements to be hybridized are positioned until reaching at least the melting point of the solder or hybridization material to join the modules and interconnection substrate together by reflow effect.
