Abstract:
1. A method for fabricating a substrate for optics, electronics, or opto-electronics, which method comprises: implanting atomic species into a face of a source substrate to form a weakened zone therein corresponding to the depth of penetration of the atomic species; transferring a seed layer on to a support substrate by bonding a face of the support substrate to the face of the source substrate and detaching the seed layer from the source substrate; depositing a working layer on the seed layer by chemical vapor deposition, high temperature chemical vapor deposition, hydride vapor phase epitaxy, epitaxy, metal organic chemical vapor deposition, or molecular beam epitaxy to form a composite substrate comprising the support substrate, seed layer and working layer; and removing the seed layer and the working layer from the support substrate to form a substrate.
