Claim Text:
1. A method for fabricating a substrate, comprising the steps of: providing a donor substrate with at least one free surface and at least one sidewall; performing an ion implantation at a predetermined depth within the donor substrate to form a predetermined splitting area inside the donor substrate at the predetermined depth; positioning the donor substrate at least partially within a recess or hole in a mold, the mold including at least one sidewall within the recess or hole having a geometry matching a geometry of the at least one sidewall of the donor substrate; and providing a layer of an adhesive paste over an entirety of the at least one free surface of the donor substrate while the at least one sidewall of the mold within the recess or hole at least partially overlaps the at least one sidewall of the donor substrate, the at least one sidewall of the mold confining the layer of the adhesive paste to a region adjacent the at least one free surface of the donor substrate.
