Abstract:
A method of manufacturing a thin film of solid material that includes at least the following steps:a step of ionic implantation through one face of a substrate of the solid material using ions capable of creating in the volume of the substrate, and at a depth close to the mean depth of penetration of the ions, a layer of micro-cavities or micro-bubbles, this step being carried out at a maximum implantation temperature for a length of time;an annealing step to bring the layer of micro-cavities or micro-bubbles to a maximum annealing temperature for a length of time; anda step of selecting a thermal budget of the annealing step so that the thermal budget for the annealing step is greater than or equal to a minimum total thermal budget necessary to obtain cleavage of the substrate along the layer of micro-cavities or micro-bubbles less a thermal budget for the step of ionic implantation less the sum of any thermal budgets inferred by steps other than the step of ionic implantation and the annealing step.
