Laser annealing of self-ion damaged silicon

Abstract
Partially damaged self‐ion implanted Si(100) has been irradiated by a ruby laser pulse (λ=0.69 μm, tp=15 ns). Channeling effect technique measurements and TEM micrographs show the reordering of the implanted layer in the laser energy range 1.5–2.5 J/cm2. No polycrystalline transition has been detected. Calculations in terms of local melting of the disordered zone explain the experimental data.
