摘要： The invention relates to a method for recycling a substrate with a step-like residue in a first region of its surface, in particular along the edge of the substrate, which protrudes with respect to the surface of a remaining second region of the substrate, and wherein the first region comprises a modified zone, in particular an ion implanted zone, essentially in a plane corresponding to the plane of the surface of the remaining second region of the substrate and/or chamfered towards the edge of the substrate. To prevent the negative impact of contaminants in subsequent laminated wafer fabricating processes, the recycling method comprises a material removal step which is carried out such that the surface of the substrate in the first region is lying lower than the level of the modified zone before the material removal. The invention also relates to a laminated wafer fabricating method using the recycled substrate and to a recycled substrate in which the surface of a first region lies lower than the surface of the second region.

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.

摘要： A donor wafer resulting from a method of recycling the wafer after detaching at least one useful layer. The donor wafer includes a substrate; a buffer structure on the substrate; a protective layer associated with the buffer structure; and a post detachment layer located above the buffer structure and presenting projections or rough portions on its surface. The protective layer prevents removal of the entire buffer structure when the post detachment layer is removed.

摘要： The invention provides a method of producing a structure of a thin layer of semiconductor material on a support substrate. The thin layer is obtained from a donor substrate and includes an upper layer of semiconductor material. The method includes forming on the upper layer a bonding layer of a material that accepts diffusion from an element of the material of the upper layer, bonding the donor substrate from the side on which the bonding layer is formed on the upper layer to the support substrate, and diffusing the element from the upper layer into the bonding layer to homogenize the concentration of the element in the bonding layer and the upper layer. The result is that the thin layer of the structure is joined by the bonding layer to the upper layer.
