Latest Patents

Marianne Coig holds a patent for a method that involves preparing a thin layer by forming a weakened zone in a central portion of a donor substrate. This method does not extend into the peripheral portion of the donor substrate. The process includes initiating and propagating a splitting wave in the weakened zone, which does not propagate through the peripheral portion. The steps of this method include joining the main face of the donor substrate to a receiver substrate, followed by a heat treatment that frees the thin layer from the donor substrate at the central portion. After this separating step, a detaching step is performed to treat the assembly and detach the peripheral portion of the donor substrate from the receiver substrate.
