摘要： A method for producing a semiconductor structure that includes at least one useful layer on a substrate. This method includes providing a source substrate with a zone of weakness therein that defines a relatively thick useful layer between the zone of weakness and a front face of the source substrate; bonding the front face of the source substrate to a support substrate and detaching the useful layer from the source substrate at the zone of weakness to transfer the useful layer to the support substrate; implanting atomic species into a free face of the useful layer to a controlled mean implantation depth therein to form a zone of weakness within the useful layer that defines front and rear useful layers, with the rear useful layer contacting the source substrate and the front useful layer containing a greater concentration of defects; bonding a stiffening substrate to the free face of the front useful layer after implantation of the atomic species; and detaching the front useful layer from the rear useful layer along the zone of weakness to form a semiconductor structure comprising the support substrate and the rear useful layer thereon. The structures obtained can be used in the fields of electronics, optoelectronics or optics.
