Abstract:
1. A process for manufacturing a stacked structure comprising at least one thin layer bonded to a target substrate, comprising the following steps: a) implantation of gaseous compounds into an initial substrate through one of its faces corresponding to a first contact face, to form a weakened layer, a thin film being defined between said first contact face and said weakened layer; b) bonding the first contact face of the thin film to an intermediate support by molecular bonding; c) fracturing at the weakened layer to expose a second contact face of the thin layer opposite the first contact face, wherein said fracturing comprises applying a thermal treatment to the structure obtained at the end of step b) d) bonding a face of a target substrate with at least part of the second contact face by molecular bonding; and e) removing at least part of the intermediate support in order to obtain the said stacked structure by mechanical and/or chemical attack.
