Description: 
The beneficial effects of F implantation on the modification of extended defects in Si have been studied. Preamorphized Si samples were implanted with F (75keV, 6×1015F∕cm2) and regrown by solid phase epitaxy (SPE) at 700°C. The formation, just after SPE, of a band of bubbles overlapping the F enriched region has been evidenced, clearly demonstrating the formation of F-vacancy (V) complexes with determined stoichiometry. Moreover, the authors demonstrate that these F-V complexes inhibit the formation of extended defects, acting as efficient traps for Si interstitials. These results represent a promising route toward point defects engineering in microelectronic application.
