We have examined Al₂O₃ /GeO_x / (111) and (100) n-Ge MOS interface properties with different annealing temperature and atmosphere. After PDA at 550 ^oC, the good MOS interfaces with the minimum D_it of ~3×10¹¹ eV^-1cm^-2 have been obtained. This result has proved that annealing at 550 ^oC used in the smart-cut process is still applicable to GOI structures.
