ABSTRACTThe effects of post implantation annealing on the properties of buried oxide silicon-on-insulator (SOI) substrates in the temperature range of 1150°C to 1300°C have been studied. Microstructural analyses showed that the crystallinity of the top silicon layer was improved at higher annealing temperature. Lower thermal donor generation at 450°C was observed in SOI annealed at higher temperature. The improvement in microstructure and lower thermal donor generation were correlated to the lower oxygen concentration in the top silicon film.

ABSTRACTEnhanced electron conductivity is observed in silicon that has been implanted with oxygen ions to form a buried oxide layer. The conductivity is attributed to donors that are created in the silicon both above and below the oxide. Secondary ion mass spectrometry and Rutherford backscattering spectroscopy show that, during subsequent annealing, oxygen accumulates only in the silicon surface. This causes the donors in the silicon surface to be easily activated to high concentrations and, unlike donors beneath the oxide, to be extremely resistant to thermal annihilation.

ABSTRACTWe have studied buried oxide formation as a function of implantation and annealing conditions. The layers appear to form via a nucleation and growth process, so the quality of the oxide and the perfection of the overlying crystalline Si layer depend more strongly on the substrate temperature during implantation than on the annealing temperature. Since it is easier to observe the layer formation process in a thin (<1000Å) layer, we concentrated on sub-stoichiometric doses and chose substrate temperatures below 400°C to stay in a homogeneous nucleation regime. Then we varied the annealing temperature from 1150°C to 1407°C. Modeling the coalescence of the oxide layer as a thermally-activated process yields activation energies of approximately 6 eV, suggesting that crystalline damage removal may be the bottleneck for this substrate temperature regime.

AbstractWe have recently demonstrated a new implantation technique called SPIMOX (separation by plasma implantation of oxygen) to synthesize silicon-on-insulator structures using plasma immersion ion implantation (PIII) process. the implantation is performed by applying a large negative bias to a Si wafer immersed in an oxygen plasma created by an ECR source. Since the technique has no mass analysis, coexistence of O+ and O2+ ions in oxygen plasma can cause a non-Gaussian profile of the as-implanted oxygen distribution. We observed that during post-implantation annealing, the ripening process of the oxide precipitates depends on depth and concentration of the oxygen peaks. IN addition, implanted oxygen can migrate towards the Si surface during annealing, preventing a continuous buried oxide layer formation. IN this paper, we report our observation on the effect of the implantation profile on the competitions between internal oxidation at different depths and between internal and surface oxidation processes. With an additional He implantation, we demonstrate that the nucleation of oxide precipitation can be enhanced.
