A method for producing a stacked structure comprises: a) providing a carrier substrate and an initial substrate, each having a front face and a back face, b) forming a buried weakened plane in the carrier substrate or in the initial substrate, by implanting light ions through the front face of either of the substrates, c) joining the carrier substrate and the initial substrate via their respective front faces, d) thinning the initial substrate via its back face to form a donor substrate e) providing a receiver substrate having a front face and a back face, f) joining the donor substrate and the receiver substrate via their respective front faces, and g) separating along the buried weakened plane, so as to form the stacked structure comprising the receiver substrate and a surface film including all or part of a donor layer originating from the initial substrate.
A method for producing a stacked structure comprising a receiver substrate and a surface film, the method comprising:
