Abstract

The invention relates to a method for transferring at least one layer of material, comprising: producing first and second separating layers (), one against the other, on a first substrate (); producing the layer to be transferred on the second separating layer (); securing the layer to be transferred to a second substrate (), forming a stack of different materials; and performing mechanical separation at the interface between the separating layers; in which the materials of the stack are such that the interface between the first and second separating layers has the weakest adhesion force, and the method comprises a step reducing an initial adhesion force of the interface between the first and second separating layers.
