Abstract:
A process for forming a thin film of material from a substrate, comprising the steps of:(a) forming a gaseous compound trap zone implantation of a layer of inclusions in the substrate at a depth corresponding to a required thickness of the thin film; (b) treating the substrate so as to introduce into the layer of inclusions, a dose of gaseous compounds sufficient to cause formation of micro-cavities in a fracture plane along which the thin film can be separated from the remainder of the substrate, the introduction of gaseous compounds involving a step of implantation of said gaseous compounds; and (c) separating and recovering the thin film from the substrate along the fracture plane wherein the substrate is placed in intimate contact with a support to which the thin film will bond after separation from the remainder of the substrate.
