H+-implantation is the basis for an ion-cut process, whichcombines hydrophilic wafer bonding, to produce heterostructures over a widerange of materials. This process has been successfully applied in Si toproduce a commercial silicon-on-insulator material. The efficacy ofimplantation to produce thin-film separation was studied by investigation of H+-induced exfoliation in Si and SiC. Experiments were done toisolate the effects of the hydrogen chemistry from that of implant damage.Damage is manipulated independently of H+ dosage by a variety oftechniques ranging from elevated temperature irradiation to a two-stepimplantation scheme in Si, and the use of channeled-ion implantation in SiC.The results will demonstrate that such schemes can significantly reduce thecritical dose for exfoliation.
