    摘要: A method of recycling a donor wafer after detaching at least one useful layer is provided, the donor wafer comprising successively a substrate, a buffer structure and, before detachment, a useful layer. The method comprises employing mechanical means to remove part of the donor wafer on the side where the detachment took place, such that, after removal of substance, there remains at least part of the buffer structure capable of being reused as at least part of a buffer structure during a subsequent detachment of a useful layer. The present document also relates to methods of detaching a thin layer from a donor wafer which can be recycled according to the invention, as well as donor wafers which can be recycled in accordance with the invention.

    摘要: The invention relates to a method of re-forming a useful layer on a donor wafer after taking off a useful layer formed of a material chosen from among semiconductor materials. The donor wafer includes in succession a substrate and a taking-off structure, the taking-off structure includes the taken-off useful layer before taking-off. The method includes a removal of material involving a portion of the donor wafer on the side where the useful layer has been taken off. The material is removed by mechanical means so as to preserve a portion of the taking-off structure to form at least one other useful layer which can be taken off after re-forming, without adding additional material to the wafer.

    摘要: A process for producing a structure of a thin layer of semiconductor material obtained from a composite structure donor wafer. The donor wafer includes a lattice parameter matching layer of a matching substrate that advantageously has an upper layer of semiconductor material having a first lattice parameter. A film of semiconductor material having a second, nominal, lattice parameter that is substantially different from the first lattice parameter is strained by the matching layer. A region of weakness is created in the matching substrate to facilitate splitting. A relaxed layer has a nominal lattice parameter that is substantially identical to the first lattice parameter. The relaxed layer is transferred to a receiving substrate. A number of different wafers can be made by this process.

    摘要: A method for transferring a layer of semiconductor material from a wafer is described. The wafer includes a support substrate and an upper surface that includes a buffer layer of a material having a first lattice parameter. In an embodiment, the technique includes growing a strained layer on the buffer layer. The strained layer is made of a semiconductor material having a nominal lattice parameter that is substantially different from the first lattice parameter, and it is grown to a thickness that is sufficiently thin to avoid relaxation of the strain therein. The method also includes growing a relaxed layer on the strained layer. The relaxed layer is made of silicon and has a concentration of at least one other semiconductor material that has a nominal lattice parameter that is substantially identical to the first lattice parameter. The technique also includes providing a weakened zone in the buffer layer, and supplying energy to detach a structure at the weakened zone. The structure includes a portion of the buffer layer, the strained layer and the relaxed layer. Lastly; the method includes enriching the concentration of the at least one other semiconductor material in the relaxed layer of the structure.
