Abstract
A method for transferring a useful layer onto a support includes the following processes: formation of a fragilization plane through the implantation of light species into a first substrate in such a way as to form a useful layer between this plane and a surface of the first substrate; application of the support onto the surface of the first substrate to form an assembly to be fractured having two exposed sides; thermal fragilization treatment of the assembly to be fractured; and initiation and self-sustained propagation of a fracture wave in the first substrate along the fragilization plane. At least one of the sides of the assembly to be fractured is in close contact, over a contact zone, with an absorbent element suitable for capturing and dissipating acoustic vibrations emitted during the initiation and/or propagation of the fracture wave.
