Method for selectively transferring at least an element from an initial support onto a final support

Process of selective transfer of labels (16, 26, 36) from an initial support (10, 20, 30) to a final support (19, 29, 39), with each label made up of at least one element (11, 21, 31) constituent of a microelectronic and/or optoelectronic and/or acoustic and/or mechanical device, the elements being made in a surface layer of the initial support, and the process including the following stages:

• a) Fixing a transfer support (14, 24, 34) on the surface layer of the initial support (10, 20, 30);
• b) removal of the part of the initial support that does not correspond to the surface layer;
• c) lateral definition of the labels, on the set made up of the transfer support and the surface:
• layer, by cutting done according to the thickness of the surface layer, the cutting being done at least in the surface layer so as to leave zones of the set to be broken off;
• d) Grasping one or several labels (16, 26, 36) to be transferred and their tearing off by input of energy in the corresponding zones of said set to be broken off, with the energy input resulting in the breaking off of these zones;
• e) Transfer and fixing of the label or set of labels torn off in stage d), on the final support (19, 29, 39).
