ABSTRACTWe show that the use of phosphorus doped spin-on glasses as diffusion source is an attractive approach for the formation of shallow junctions in polycrystalline silicon materials. Moreover, this very simple doping process using a glass film can be fruitfully associated to rapid thermal annealing.

AbstractWe studied reverse leakage current in n+/p titanium-salicided shallow junctions using C49 Ti-silicide as a diffusion source. After Ti deposition, rapid thermal annealing (RTA) was performed to form the C49 Ti-silicide. Subsequently, arsenic ions were implanted and a 2nd RTA was carried out at 850 °C to form the low resistivity C54 Ti-silicide. In spite of no drive-in process following the 2nd annealing, the implanted As diffused well into Si substrate and the reverse leakage current of the n+/p junctions was reduced to two orders of magnitude lower. Since the high chemical affinity of As to Ti-silicide trapped the dopant in the silicide, it has been known that Ti or Ti-silicide cannot be used as a diffusion source. However, in this work, we found that the C49 Ti-silicide acted as a diffusion source of As ions. The reason of fast diffusivity is attributed to the generation of high tensile stress induced by As implantation.

AbstractConventional and Rapid Thermal Annealing of Semi-Insulating Polycrystalline Silicon layers obtained by Low Pressure Chemical Vapor Deposition (LPCVD) from disilane Si2H6 have been performed in order to determine the structural modifications induced on the layers by these thermal treatments. The study of these modifications has been carried out by several analysis methods like FTIR, XPS, TEM, RAMAN and ellipsometry. The results obtained are presented, contrasted and discussed in this work.

ABSTRACTDouble-diffused shallow junctions have been formed by ion implantation of both phosphorus and arsenic ions into silicon substrates and rapid thermal annealing. Experimental results on defect removal, impurity activation and redistribution, effects of Si preamorphization, and electrical characteristics of Ti-silicided junctions are presented.

ABSTRACTThe formation of titanium suicide over polycrystalline silicon has been investigated after rapid thermal annealing treatment in nitrogen and argon ambients. After rapid thermal annealing 300 Å thick titanium overlayer at 900°C for 10 seconds, the sheet resistance of about 3 Ω/□ was achieved, which decreased to 2 Ω/□ after 1100°C / 10s treatment. The TiSi2 Phase was found to be stable after RTA treatments up to 1100°C /10s with no or negligible migration of titanium along the grain boundaries in polycrystalline silicon. In the nitrogen ambient, an external layer (titanium rich, mixture of titanium oxide and nitride) was observed to form after the RTA treatment, but the surface was found clean in the argon ambient.
