ABSTRACTThe formation of single crystal multiple layers on silicon substrates with thicknesses in excess of 1 μm has been demonstrated to be a viable process. Film build-up is via repetitions of the steps (1) pre-deposition chemical cleaning of wafer, (2) magnetron sputter deposition of 0.3 pm thick amorphous Si, (3) interfacial mixing via 190 keV implantation of Si, and (4) film epitaxial crystallization via pulsed laser annealing. Doping has been demonstrated by both (1) P ion implantation and (2) P incorporation from PH3; included in the sputter gas ambient.

Arsenic doped amorphous silicon layers have been deposited on silicon single crystals by R.F.cathodic sputtering of a silicon target in a reactive argon-hydrogen mixture, and annealed with a Q-switched Ruby laser. Topographic analysis of the irradiated layers has shown the formation of a crater, due to an evaporation effect of material which could be related to the presence of a high concentration of Ar in the amorphous layer. RBS and Raman Spectroscopy showed that the remaining layer is not recrystallised probably due to inhibition by the residual hydrogen. However, it was found that arsenic diffuses into the monocrystalline substrate by laser induced diffusion of dopant from the surface solid source, leading to the formation of good quality P-N junctions.

ABSTRACTHigh-dose ion implantation (1017 ions-cm−2) of C+, N+, and O+ at 50 KeV into silicon followed by pulsed laser annealing at 1.06 μm was studied. Formation of SiC, Si3N4, and SiO2 has been observed and investigated using Transmission Electron Microscopy (TEM) and Differential Fourier-Transform Infrared (FT-IR) Spectroscopy. Furthermore, in N+-implanted and laser-annealed silicon samples, we have observed a cell-like structure which has been identified to be spheroidal polycrystalline silicon formed by the rapid laser irradiation.

We report on the effect of high repetition pulsed laser annealing with a KrF excimer laser on the optical properties of phosphorus ion-implanted ZnO nanorods. The recovery levels of phosphorus ion-implanted ZnO nanorods have been measured by photoluminescence spectra and cathode luminescence (CL) images. After ion implantation on the surface of ZnO nanorods, CL was disappeared over 400 nm below the surface due to the damage caused by ion implantation. When the annealing was performed at a low repetition, CL was recovered only shallow area below the surface. The depth of the annealed area was increased with the repetition rate of the annealing laser. By optimizing the annealing conditions such as the repetition rate, the irradiation fluence and so on, we have succeeded to anneal the whole damaged area over 400 nm in depth and to observe CL. Thus, the effectiveness of high repetition pulsed laser annealing on phosphorus ion-implanted ZnO nanorods was demonstrated.
