摘要
Recent results on extended defect formation after ion implantation are reviewed. Interstitial evaporation from {311} extended defects dominates transient diffusion over most of the range of temperatures, times, and dopant concentrations of technological interest. The reactions between interstitials and impurities are investigated by measuring the effect of O, P, B, and C impurities on {311} defects. Interstitial traps such as B and C exert a strong influence at concentrations > 10(18) cm(-3) Damage and defect formation are characterised for very shallow implants (2-5 keV Si). Even above the amorphisation threshold, stable {311} defects dominate the microstructure, despite the proximity of the surface.
