Photoluminescence of Extended Defects in Silicon-on-Insulator Formed by Implantation of Oxygen
Keyword(s):
AbstractPL and TEM have been carried out on SIMOX structures before and after thinning the silicon overlayer by a process of sacrificial oxidation. The implantation and high temperature annealing schedules involved in fabricating SIMOX material result in threading dislocations and stacking fault tetrahedra and pyramidals in the silicon overlayer. The optical activity of these extended defects is found to be low. However, after the sacrificial oxidation, strong dislocation related luminescence is observed, which is attributed to the presence of oxidation-induced stacking faults now present in the overlayer.
