    • The present invention relates to a method forfabricating a substrate (1) of semiconductor on insulatortype, comprising the following steps: - formation of an oxide layer (20) on a donor substrate (10) or a receiver substrate (30), - implantation of atomic species in the donor substrate so as to form a weakened zone(12), - bonding of the donor substrate onto the receiver substrate (30), the oxide layer (20) being at the bonding interface, - fracturing the donor substrate in the weakened zone (12) and transferring a layer of the donor substrate to the receiver substrate (30), - recycling of the remainder (2) of the donor substrate to form a receiver substrate (40) used for fabrication of a second semiconductor on insulator type 10 substrate. Before the oxidation step, a layer(14) of semiconducting materialis formed by epitaxy onthedonor substrate (10). In the implantation step, the weakened zone (12) formed in said epitaxied layer (14) so that the transferred layer is an epitaxied semiconducting material layer (140). And the donor substrate (10) is chosen comprising oxygen precipitates with a density of less than10 10 /cm 3 and/or a mean size of less than 500 nm.

    • The invention relates to a method for creating a structure comprising a thin semiconductor material layer on a substrate, comprising the following steps: a species is implanted underneath a surface of a donor substrate wherefrom the thin layer is to be made in order to create an area of embrittlement inside the thickness of the donor substrate; the surface of the donor substrate which underwent implantation is placed in intimate contact with a support substrate; the donor substrate is detached at said area of embrittlement in order to transfer part of the donor substrate onto the support substrate and to form the thin layer thereon. The invention is characterized in that the implementation step involves co-implementation of at least two different atomic species in order to minimize low frequency roughness in the structure obtained after detachment; the method also comprises a finishing step comprising at least one rapid thermal annealing operation in order to minimize high frequency roughness in the structure obtained after detachment.
