The interstitial-type {311} planar defects introduced in wafers synthesized by separation by implanted oxygen (SIMOX) have been investigated by photoluminescence (PL) spectroscopy and transmission electron microscopy (TEM). Deep-level PL of low-dose SIMOX wafers with doses of 2, 4, and 6×10^<17> cm^<-2> were analyzed under various excitations with different penetration depths. In as-implanted wafers, the 0.903 eV line associated with the {311} defects appeared in the region below the oxygen implanted layer. Correspondingly, TEM observation revealed rod-like defects due to the {311} defects in the same region. After annealing, the 0.903eV line disappeared and dislocation-related lines became visible. These results indicate that the {311} defects are generated below the implanted layer and are extended to dislocations after annealing.
