Zusammenfassung:Systems and methods are described for transfer of a thin-film via implantation, wafer bonding, and separation. A method for transfer of a thin-film, includes: implanting a source crystal with ions along a crystallographic channel and at a temperature of at least approximately 200° C. to i) form a strained region and ii) define the thin-film; then bonding a surface of the thin-film to a target wafer; and then separating a) the target wafer and the thin-film from b) a remainder of the source crystal along the strained region. The systems and methods provide advantages because the electrical carriers in the crystal, and consequently the thin-film, are not deactivated and the quality of the transferred thin-film is improved.
