Abstract
The invention relates to a method for characterizing a donor substrate, aiming to determine whether this donor substrate is likely to trigger the appearance of defects in a layer exfoliated by ion implantation. The characterizing method comprises an analysis by X-ray diffraction of a region of the front side of the donor substrate, after the donor substrate has been implanted, so as to produce digital angle-of-incidence / intensity data defining a diffraction pattern. The method also comprises a step of processing the diffraction pattern to deliver an indicator quantifying the risk of triggering the appearance of defects in an exfoliated layer of the donor substrate.
