A method for producing an aluminium nitride (AlN)-based layer on a structure with the basis of silicon (Si) or with the basis of a III-V material, may include several deposition cycles performed in a plasma reactor comprising a reaction chamber inside which is disposed a substrate having the structure. Each deposition cycle may include at least the following: deposition of aluminium-based species on an exposed surface of the structure, the deposition including at least one injection into the reaction chamber of an aluminium (Al)-based precursor; and nitridation of the exposed surface of the structure, the nitridation including at least one injection into the reaction chamber of a nitrogen (N)-based precursor and the formation in the reaction chamber of a nitrogen-based plasma. During the formation of the nitrogen-based plasma, a non-zero polarisation voltage Vmay be applied to the substrate.
