    Abstract: The present invention relates to a method of manufacturing a wafer comprising a single crystalline bulk substrate of a first material and at least one epitaxial layer of a second material which has a lattice different from the lattice of the first material. The present invention provides a method for manufacturing a wafer in which a layer which is lattice-mismatched with the substrate can be grown on the substrate with a high effectiveness and high quality at a low cost. A roughening step is included for roughening the surface of the bulk substrate and a growing step is included for growing the second material on the rough surface with a reduced number of threading dislocations and an enhanced strain relaxation compared to a second material that is epitaxially grown on a polished surface.

In an embodiment, the technique includes providing a donor wafer having a first semiconductor layer and a second semiconductor layer on the first layer and having a free surface; coimplanting two different atomic species through the free surface of the second layer to form a zone of weakness zone in the first layer; bonding the free surface of the second layer to a host wafer; and supplying energy to detach at the zone of weakness a semiconductor structure comprising the host wafer, the second layer and a portion of the first layer. Advantageously, the donor wafer includes a SiGe layer, and the co-implantation of atomic species is conducted according to implantation parameters adapted to enable a first species to form the zone of weakness in the SiGe layer, and to enable a second species to provide a concentration peak located beneath the zone of weakness in the donor wafer to thus minimize surface roughness resulting from detachment at the zone of weakness.

    Abstract: The present invention relates to a method for transferring a thin useful layer from a donor substrate having an ordered crystalline structure to a receiver substrate. The method includes creation of a weakened zone in the donor substrate to define the layer to be transferred from the donor substrate. The crystalline structure of a surface region of the donor substrate is disturbed so as to create a disturbed superficial region within the thickness of the donor substrate, and thus define a disturbance interface between the disturbed superficial region and a subjacent region of the donor substrate for which the crystalline structure remains unchanged. Next, the donor substrate is subjected to a recrystallization annealing in order to at least partial recrystallize of the disturbed region, starting from the crystalline structure of the subjacent region of the donor substrate, and to create a zone of crystalline defects in the plane of the disturbance interface. One or several species are introduced into the thickness of the donor substrate to create the weakened zone, with the species being introduced with introduction parameters that are adjusted to introduce a maximum number of species at the zone of crystalline defects.
