Defect engineering for SIMOX processing R.
For O implantation a "good match" of combinations of ion energy (E) and ion fluence (Φ) was reported for which the materials parameters were at the best and for which the lowest fluence was found to form a continuous oxide layer [11-13].
However, defect engineering brings about narrow BOX oxide layers outside the good matching as well.
Experimental In this study a cavity layer was applied for defect engineering.
