Abstract

High doses of oxygen were implanted in silicon to produce stoichiometric buried oxide structures. Microstructural analysis was performed using transmission electron microscopy, electron energy loss spectroscopy, and Rutherford backscattering/channeling techniques. Cavities were observed in the top silicon layers of the as-implanted samples in two forms: spherical cavities (30–300 Å in diameter) in the first 1000 Å below the surface, followed by a 500 Å wide lamellar array of elongated cavities. A post implantation annealing was carried out at temperatures between 1150°C and 1250°C for 3 h during which the cavities became faceted and a denuded zone of 400 Å was formed. However, with a 1300°C anneal the cavities disappeared and the density of the two prominent types of defects, namely precipitates (mostly amorphous, but occasionally crystalline) and dislocations, decreased significantly. The silicon-oxide interface became increasingly planar. Possible mechanisms of annealing of the cavities, the precipitates, and the associated planarization of the interface are proposed.
