    Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of forming a stressed region in a selected manner at a selected depth (20) underneath the surface. An energy source such as pressurized fluid is directed to a selected region of the donor substrate to initiate controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving action provides an expanding cleave front to free the donor material from a remaining portion of the donor substrate.

    Abstract: A method for producing a device comprising a membrane of piezoelectric nature above at least one cavity comprises:



    a) providing a carrier substrate having a cavity opening out onto its front face, the cavity having a lateral dimension larger than 30 μm;
    b) providing a donor substrate having a buried weakened plane delimiting a surface layer;
    c) depositing, on the front face of the donor substrate, a stiffening layer made of piezoelectric material having a thickness greater than 500 nanometers;
    d) joining the carrier substrate and donor substrate; and
    e) splitting the donor substrate at the buried weakened plane so as to transfer the membrane comprising the surface layer and the stiffening layer to the carrier substrate.
