ABSTRACT
High-temperature oxygen ion implantation has been used to form buried oxide layers in silicon single crystals. The ion implantation and substrate variables, particularly the substrate temperature, were optimized to obtain silicon layers with controlled microstructures near the surface. The as-implanted specimens were subsequently annealed at high temperatures to form a buried SiO2 layer with sharp interfaces and to minimize dislocation densities in the top silicon layers. The specimens were characterized by cross-section transmission electron microscopy and these results were compared with those obtained using spectroscopic ellipsometry. We discuss the application of the nondestructive scanning ellipsometry technique in the characterization of silicon-on-insulator materials.

    The evolution of {113} defects as a function of time and depth within Si implant-generated defect profiles has been investigated by transmission electron microscopy. Two cases are considered: one in which the {113} defects evolve into dislocation loops, and the other, at lower dose and energy,...

    We report the measured dependence of the near-infrared optical emission from sulfur-related impurity centers in crystalline silicon on the sulfur concentration in the sample. The results suggest that each impurity complex contains only a single sulfur atom. Additional experiments support the...
