Abstract: Methods for forming a semiconductor structure are described. 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.

Abstract: A method for forming a structure is provided and includes implanting an atomic species into a donor substrate having an upper surface at a given depth relative to the upper surface to form an embrittlement zone in the donor substrate, the embrittlement zone defining a removable layer within the donor substrate. The method further includes assembling the upper surface of the donor substrate to a receiver substrate. Additionally, the method includes detaching the removable layer from the donor substrate at the embrittlement zone, thereby forming a detachment surface on the removable layer, by high temperature annealing. The high temperature annealing includes a temperature upgrade phase to a predetermined maximum temperature, maintaining the maximum temperature for a predetermined exposure duration, and a temperature downgrade phase. The maximum temperature and the exposure duration are selected so as to prevent the appearance of significant defects at the detachment surface.
