    Notes: Abstract High power density electron beams offer new opportunities for studies of epitaxial growth of semiconductor materials. Assuming that the mechanism of epitaxial growth can be understood as a surface melting followed by supercooling regrowth, the heat flow equation has been applied to calculate the temperature reached after an electron beam pulse of power density between 0.5–2 J/cm2. Comparison with laser annealing is made.

    Notes: Abstract Using a pulsed ruby laser (λ=0.69 μm, FWHM=20ns) we have measured the variation of the surface reflectivity during laser irradiation. The melting depth has been measured after repetitive irradiations in order to induce diffusion of dopants to the maximum melt depth. Agreement with thermal model is found. Experimental measurements of time-resolved reflectivity on 1000 Åa-Si onc-Si are explained with the thermal model introducing a low thermal conductivity of 0.002 cal/(cm · s · K) in amorphous silicon.

    Notes: Abstract Ultrathin gate oxides (90–300 Å) have been grown on silicon under dry oxygen using a lamp light heater. The oxidation kinetics is quite different from that expected in conventional furnace oxidation since the process is shown to be diffusion limited. Infrared absorption analysis shows neither shift nor broadening of the Si-O stretching mode, indicating that the rapid oxide is stoichiometric with a good structural order. The electrical characteristics of Al-gate capacitors assessed byC-V andG-V measurements with thickness as parameter shows a good quality for oxide films thinner than 100 Å. For thicknesses higher than this value, cleaning techniques and post-oxidation annealing must be used.
